I actually know I'm not being unreasonable but my reaction may be out of proportion and I need help wording my response for my desired outcome - solitude.
I'm on a sort of retreat in Italy. Tomorrow I arranged to go on a day trip away from the base to look at some art. I'd arranged for the car to the station, bought my train ticket and was looking forward to it. I told my next door room mate who told someone else who over dinner tonight said he was coming along 'if I didn't mind.' Of course I don't mind him going to the town and looking at the art. If he is here a week it is his opportunity. Of course I don't mind if he catches the same train - although, honestly, I don't want to chat and be friendly and 'on' for an hour plus on the train there (and back?!) Why should I?
I do not want to spend 6 hours going around museums galleries, churches, having lunch, with a stranger. I prefer to look at art alone at my own pace and have my own responses. But over dinner I could hardly say that. The prick (pardon me) cornered me. I am so angry I'm finding it hard to relax. This may be disproportionate. The thing is I am quite able to be cold and freeze people if I feel like it - but I don't want to introduce awkwardness let alone animosity. I am meeting the driver of the retreat tomorrow morning and this other unwanted guest. I don't want to stop him if this is his one chance to go to the town. But I refuse to have my day stolen from me because I end up being polite to this man. I need a healthy middle ground. I am 46. I can't believe I am still being imposed on like this. I don't want to snap but I may.
Thanks for hearing me out. Perspective needed. This has touched a nerve you can tell. I would just never ever do this.
