So a friend I've known for about 10 years asked me to look after her elderly father, her homestay student and 10 year old daughter for three weeks while she's overseas do-gooding at some universal peace federation thing. I said no because I've previously looked after her kid and homestay for two weeks on another trip she took last year. She then goes and asks my mother (who I'm currently living with) if she can do it. Mum agrees and because she's fed up after being here for a week - I've had to fill in for a few days. I work full time (while said friend is on a single parent benefit getting paid not to work) and I feel really resentful my weekends being taken up by something I said no to in the first place. The other thing is I have to come back for a couple of days over my Easter break as my mum has something on. I know my friend is a single mum and needs support but I feel like she's taking the piss. Mum made it clear she hasn't got alot of money so was okay to do it if it wouldn't cost her. My friend has left NO money. Saying it shouldn't cost my mum anything. She has left a fridge full of food and will get groceries delivered though. The other thing is that it's school holidays so the 10 year old will need entertaining. We can't just stick her in front of the TV for 2 weeks. Feeling just about ready to let this friendship go!!
