A girl I used to know at university. I have honestly lost count of the huge amount of annoying and irritating things that she did. She was exceptionally, exceptionally immature. She only dated virgins and was into sk8r kids even though she was in her 20s.
We actually ended up living in the same house and she refused to pay her share of the gas bill. I couldn't afford to pay it either so ended up having to ask her dad who completely ignored my request for help. She protested she couldn't afford it, so I opened her bank statements to see hundreds and hundreds of pounds in her account.
We also had a landline in the house which only she wanted, we only agreed to shut her up. She only wanted it to talk to some guy in Switzerland who she'd met on the internet. She had to pay for that one in the end - only because she enjoyed talking to the Swiss guy.
The list goes on and on. The last time I saw her went like this. It was after this I vowed never to see her again. It was really the last straw. We were out for curry one evening.
Her: Um.. I've finished my meal now.
Me: Yes, I can see....
Her: Maybe you should be quicker!
Me: I don't understand. We've got ages till they shut, it's only 9pm....
Her: But I have to go now.
Me: What? Why?
Her: I have a train at 915pm.
Me: What? Why didn't you mention this before?! We haven't been here an hour!
Basically she'd squeezed me in just before her train so she didn't have to be bored for an hour, and hadn't told me in case I thought it wasn't worth it. She drove me mad, that girl. Sufficed to say I shan't be seeing her again.
