<text>  After handing her teacher a sick note to skip the days PE lesson - Olivia McEvoy thought she had pulled off the perfect crime.

The 27-year-old mother-of-two, of Cheshire, said Olivia was perfectly fit to take part in the class and asked the teacher Mr Whittle to show her daughter the letter after reading it. Stitched up: The note above Olivia McEvoys mother Samanatha wrote for her after she said she was too cold to go to her PE lesson . Surprise: Ms McEvoy said her daughter Olivia had a severe case of bone-idle-itus and suggested she did a few extra laps to warm her up . She posted a picture of the note on Facebook, which has since gone viral with more than 3,000 shares. It was accompanied with the comment: Well here you go Olivia heres your note for PE, it will be sealed in an envelope ready for her to hand to the head in the morning. The Year six pupil unwittingly limped into class at St Johns C of E Primary school in Sandbach, Cheshire, citing that she had a bad leg and even giggled to friends that she had got out of PE. The joke was revealed when the headmaster - who was in on the plan - read the letter and called Olivia into his study where he told her: There are things in life we dont enjoy but have to do them. Foiled: The Year 6 pupil, pictured with her father Wayne and brother Kaylan right, unwittingly limped into class at St Johns C of E Primary school in Sandbach, Cheshire, citing that she had a bad leg . Olivia then discovered her PE kit had already been dropped off at reception after her scaffolder father Wayne, 34, had secretly given it to a classmates mother who was taking them to school that day. Ms McEvoy said: Unfortunately she didnt have to do the extra laps but she actually really enjoyed PE and had a good lesson. But she wasnt speaking to me at all - not for the rest of the night. When she got picked up by Wayne she had a face like thunder. She didnt speak to him. It was parents evening that night and all the teachers thought it was hilarious. It was like an episode of Absolutely Fabulous, I call her Saffy because she is so clever and sensible. When she came home she said, mum I do not know why you think its so funny which made it all the more amusing. We couldnt stop giggling when we wrote the letter. We had to search the house top to bottom for an envelope to keep the plan secret. Ms McEvoy, who also has a three-year-old son called Kaylan, said she and her husband played the prank after Olivia came downstairs no fewer than a dozen times to nag her about writing the fake letter. Harsh lesson: Olivias mother said: Theres no chance shell be doing it again in a hurry. Its a lesson to her that she cant get out of things she doesnt like She said: She has tried every trick in the book to get out of PE. In the run up to this she has left her kit at home, only taken one shoe to lessons, has a tummy ache, her foot hurts - the teachers know her very well. She doesnt like to move at all. Shed rather sit on her i-Pad or games console. It was about 10.30 pm and she was up and down the stairs, saying please write me a note, Ill do anything, Ill make you a brew, Ill clean, Ill look after Kaylan. I kept saying, you are not having a note and sent her back to bed. In the end when she came down again I shouted, get me a pen and paper then. She added: I said so whats wrong with you? and she told me to write she that had a bad leg. She just didnt want to move and said it was too cold. She said that upon agreeing to say that she had a sore leg, Olivias face lit up before she tottered off to bed none the wiser. Played th part: Olivia, pictured with her little brother Kaylan, even walked into class with a limp so that teachers would believe her made-up injury . The mother added: She thought she was a winner. Wayne and I were literally sat there wetting ourselves writing this letter. Then I realised wed need an envelope so she couldnt read it. It was 11pm and we were running around the house looking for an envelope. It was like we were the kids. Ms McEvoy then took to Facebook to disclose to a few of her friends what she had done, posting a picture of the note before it went viral. She added: Everyone was saying I was terrible and couldnt believe I was going to send her with it. I cant believe how many people have shared it but I thought it was absolutely hilarious. Theres no chance shell be doing it again in a hurry. Its a lesson to her that she cant get out of things she doesnt like.
