I get pissed when I call but my mate doesn't pick up. And then this mate of mine has the audacity to reply a text message saying "I'll pick up tomorrow."
Fuck lah. Ok, so said  mate is going through personal problems, but said mate should try to be at least a little bit decent to me.
Fine.
Doesn't this said mate know that I am feeling as guilty as hell thinking about the personal problem?

I may not be involved in the problem, but I still feel guilty.
