Annoyed

I'm trying to work what has pissed me off more today. It is either the fact that the milk that I brought from a shop today had gone off so badly it had gone fizzy that I have no chance of being able to bring back as they will deny I brought it there without a receipt (because it's milk!), or people who don't say 'please' or 'thank you'. Thinking about it, the second one has pissed me off slightly more, as I think it is common courtesy to actually recognise that someone has done you a favour. I only spent 69p on the milk, and I could probably turn it into some kind of lovely metaphor for what I think about that certain institution if I felt like it. Then again, it is 69p that I could have spent on... oh, how about fresh milk!
I think this week is going slower because of the exams and the grey skies in May. Oh well, it feels like I have extra time to revise and knit.
