text: Tom: have you finished your homework?
  Frank: not even started, just downloaded Gods of War XD
  Tom: hahaha, right :D so you won't help me physics
  Frank: Eh... I haven't even looked at it yet
  Tom: kk, will write to Karen, number 6 is a bitch
  Frank: uhm, isn't this optional though?
  Frank: I think I remember Heyes saying you can do it if you want extra points...
  Tom: really?! see, you did help me with physics :D
  Frank: hahaha, wanna come?
  Tom: Gods of War? on my way :D
target: Tom has a problem with number 6 in his homework. It turns out it's optional, so he goes to Frank to play Gods of War.
