No I wouldn't like it. 3-4 miles away yes, maybe, but not within a stone's throw. Then again my mother had a tendency to be a critical, moany, needy individual who made me feel bad if I didn't visit her 2-3 times a week, despite me having a job, and 2 DC, and my own home! I lived 5-6 miles away which was OK, but I sometimes wished I lived 100 miles away!
My younger brother lived just half a mile away from her, and he never had children - at the time - but she never expected him to step up/come around/visit 2-3 times a week/do chores and shopping for her. 
There's a bit of a weird co-dependency going on with some families I know. eg, one family I know in my village, have 15 family members all living within 2-10 minutes walk of each other; the nan and grandad, (both mid 70s,) and their 3 adult children. (2 sisters and a brother in their 40s.) Then there's the sisters 2 husbands, and then there is the 4 DC of the 2 sisters...all in their 20s. (The brother is single and still lives with nan and grandad, at 45.) Then 2 of the 4 DC have husbands too, and 1 child each. They all live in the village, and every single one of them would only have somewhere in this village to live, near mum and dad and nan and grandad. They all refuse to live anywhere else.
They're in and out of each others pockets and the 2 sisters are always running around after their parents, running errands and visiting them every day, despite having jobs! The 2 young adults who have 1 child each are always in each other house, or their mum and dad's or their grandparents. Hugely co-dependent and needy IMO, and they don't seem to have any friends. Very insular.
