Good idea for a thread DG!
I wish I'd not gone to uni.
I wish my cat was still alive (never thought it was possible to love an animal so much).
I wish my Dad would call me more.
I wish I had one decent best friend who leaves me sickening-to-others-BFF messages on my FB wall and texts me just to say hi and that I can go and have nights out with (This one's a particularly sore subject at the moment).
I wish uni didn't involve so much group work.
I wish I had enough money to get a better flat that's not currently cold, damp and mouldy.
I wish I lived closer to home.
