I belong to my local group Nextdoor, and there have been a couple of posts from people asking for things, eg. a woman saying she has no birthday presents to give to her son and can people donate, and another person saying their daughter is moving into a flat and can't afford any furniture and asking for a bed, sofa, etc.... all the basics.
These people may be genuine or they may not. Hard to know, but I got caught out many years ago when my daughter was a toddler and we were extremely hard up. I had just walked back from the shops in the rain with my daughter in the buggy when there was a knock at the door and a woman was standing there with a toddler not wearing a coat in the pouring rain. They were soaked.
She asked me for some clothes for her toddler and I felt so sorry for the little girl, so I suggested she come back in 10 minutes while I sorted out some of my daughter's clothes. I gave her a large bagful which we couldn't really spare but I couldn't bear to see that poor wet little girl.
Then I watched them walk down the road and get into a new car and drive off! 
Since then I am very wary of requests.
Anyone else been caught?
