I have an elderly neighbour who I take to a regular church thing once a week. It is out of my way and is a bit of a pain because it is at lunchtime and DC4 still has a nap so I have to juggle my day a bit to do it, but I don't mind as it is something that I committed to do, and I know that it gives her a lot of pleasure.
I have seen her a few times struggling to the supermarket and have offered on many occasions to go and get whatever she needs, and rarely she takes me up on it but she does occasionally.
Recently she's started phoning me up and asking me to take her to doctors/physio appointments (and then waiting around for her) before taking her home. I have two preschoolers and one at school so it's not as though I don't have anything else to do!! I find it very hard to say no to anyone because I do like to help if I can, but recently I've felt a bit pressured to say yes, even if it isn't frightfully convenient or easy to do stuff for her.
She has two daughters, one of whom lives locally, and she's been going to the church for 50 years so AIBU to think that she could ask someone less tied than me sometimes? Or do I just need to learn to be a bit more assertive and say no when it's not convenient....
