text: Natasha: Hi Richard, how are u? what did you do with the students this Wednesday?
  Richard: Oh hi, sorry I haven't replied you earlier. We did the second chapter.
  Natasha: Do you want me to prepare a test for them?
  Richard: there's no need for that, they are having a test with me next Wednesday
  Natasha: OK, so I'll start the third chapter with them
  Richard:  <file_gif>
  Natasha: Tom, can you send me the test u made?
  Richard: no problem
  Natasha: thx
  Richard: the first test went ok, but some of them failed miserably
  Natasha: the first group is terrible, I feel we're moving through molasses
  Richard: really? they wrote the test better than the second group
  Natasha: :O for real?
  Richard: yep, and the second group always goes slower than the first one
  Natasha: if you say so
  Natasha: but tbh I prefer the second one, they seem more energetic and active. I hate classes where I feel like a bad stand-uper
  Richard: lol
  Natasha: OK, so I'll start the 3rd chapter with them and I'll let u know where I managed to get with them
  Richard: good luck ;)
target: Natasha doesn't need to make a test for the students, as Richard is making one next Wednesday. Natasha and Richard have different opinions about the two groups.
