Reasons for going:
I will feel bad if I don't.
I can't go tomorrow and didn't go yesterday.
It's good for me!
Reasons not to go:
I have sore throat. It's not awful but I have that feeling you get at the start of a cold when it's got that nasty scratchy feel to it.
Actually that's my only reason for not going! I've been a bit run down lately (probably sleep deprivation) so part of me doesn't want to risk making things worse and another part of me thinks I am just being lazy!
