I Forgive and forget;

For instance:

• I had plans to move in with a girl from college. We'll call her X.
• I start looking for housing a few weeks before college starts
• she's away travelling so I txt her telling her about the house.
• she doesn't like the house, says If I want to move there I can knock myself out.
• I do just that, since it's a great house right opposite college. I ask another friend (who is fabulous and I enjoy living with much more, I now realise, than I ever would've enjoyed living with the other girl) to move in instead. We'll call her S.
• I know that X has another friend who already has a backup living arrangement for X, so I'm not leaving her with no housing or anything.
• college starts. On the first day I pick a desk next to my housemates.
• X missed the first day of college. she arrives later and shoves all the stuff off of my desk while I'm not in the room (yes it had my name on it)
• I get myself a makeshift desk.
• S tells me that X visited her in the place where she works at the weekends and started bitching about me. apparently she's hugely pissed at me for 'annoying' her while she was travelling.
• I act like nothing happened. smile, converse, compliment new hair style, help with her college work, as if nothing happened.

some part of me is tempted to exact some kind of fitting revenge.. I could give her the wrong essay title to work on maybe.. or I could remove her desk. or maybe cover it in spray glue.
But I wont. that, to me, would be the 'bad way' of dealing with it. It wouldn't lead anywhere but to a silly, petty fight that would in the end help nobody. Maybe I should at least confront her, but again, I doubt anything good would come of it.
