I totally understand where OP is coming from re: not wanting to help just anyone who asks, after an astonishing incident that happened just after we moved house - a few months in the new area, but it was the first time I met the neighbours of our neighbours, i was chatting to the oldish (but not eldery) wife of the couple at a local gathering (Christmas event). She drove, had no caring responsibilities of her own, GP and hospital all within a 20min drive with ample parking, etc.
i'd barely had time to introduce myself, explain which house we'd moved into, before a very interesting comment was made - it was something like "oh you must give me your number in case you can ever do anything for me."
I thought that was odd phrasing - not "so we can see if we can help each other out". not that.
i brushed off the comment and enjoyed the rest of the party, only to learn that the woman asked a couple of other neighbours for my number over the next few weeks (fortunately they didn't have it at the time!).
Now i know what a bullet i dodged - this couple have 3 kids who all live internationally, refuse to pay for any help like a cleaner or gardener, and are on driving a constant set of expectations that neighbours will come and help (who in our case, they barely know, i'm not even convinced she could tell you my name).. collecting prescriptions.. weeding the path, collecting parcels.. making a phone call to the bank, the list is endless.
Whereas there I was, 6 months pregnant and running on fumes trying to keep down a highly-pressured, high-travel-intensity job after a very stressful long-distance move.. and this 65 year old neighbour thought I existed because "in case you can ever do anything for me"?!?!!?!
Until that lightbulb moment i've always been a bit of a people pleaser, and whenever anyone looks like they're a piss taker these days, i think back to the bullet i dodged there - there are some people in life that just take, and take and take.
I'm not saying I don't do favours for people these days,but i always try and remember if I say yes to that person, they need to be close to me, and deserve it, and on balance would be someone who'd help me out in the future - I look back to how i was in my 20s, and i think - why did i give so much away to others who didn't value it? That's time, money and energy that i should have spent on myself.
I'm with the OP on this one - unless there's missing context like the lady is genuinely at the end of her options, it's an emergency, no taxi firm can cover the trips - sorry, but there are other options. It's not up to OP to fix other people's lack of exploring them!
