A friend of mine bought a cat, despite knowing that she and her family have numerous weekends away with a reenactment society throughout the year.
Every time they go away she asks me to go and feed the cat and let it out/in the morning and evening. I live 2 miles away so have to drive and I have my own family and little girl to look after so it's not exactly convenient. After the first few times I did it I got fed up because she clearly took it for granted that I'd just keep doing it. I barely got a thank you, let alone a token of appreciation (which personally I would've given if it were the other way around). I know 2 miles isn't far but the petrol soon mounts up as it's 8 miles a day.
She's just announced that they're going away for a week soon and when I asked if she'd booked the cat into a cattery she just said "I've not decided what I'm doing with him yet". I think she's totally irresponsible for booking the holiday without ensuring she has care for her pet. I know she'll ask me to go morning and night each day and I'm just not prepared to do it for someone who doesn't seem to appreciate the inconvenience it causes.
I used to class her as a good friend but over the last year but I certainly wouldn't now.
