Are you sure you really need help?

So as I drive to work I always notice people asking for help or money. Now back in the day I used to always feel sorry for some of these people. I would always try to give them some money until my dad noticed some getting out of a BMW or another nice looking car. We mean nice and new not a clunky old BMW that needs to be trashed. So I sort of stopped but sometimes I wondered if some of those really need help. I mean I know there are shelters and all but sometimes that is just not enough. So I wonder if most of those people asking for money truly need it or the ones that do not. So a couple of days ago I saw one holding a sign saying Family in need, anything will help. The problem I saw or noticed was it was just one person out there. So I wondered, where was this other family, if the other family members too frail to move or are they just little kids. Anyway that would got me and I wanted to ask about the other members but I was unable to. But I will say at least these people but in a lot for effort than the ones that need money usually for some sort of drug. Because one day A guy hit me for me. It seems that he needed money to take a Taxi because him and his baby girl need to get to Edmond. Mind you at the time I lived In Norman. So how much did he ask for. 30 dollars, 50 dollars, 100 dollars. Nope, just 5 or 10 dollars. Very interesting!! Especially since I wish I could go to Edmond off 10 dollars. Man I would take that Taxi anywhere. I could probably go to Dallas for 50 dollars. So I think a week later, I saw him again. Of course without the baby girl but once again asking for money. Of course for him I had none, I wondered if he saw me with stuff and just kept pestering me. So later one during the course of my stay at the apartment I saw two girls as I was leaving for the Wal-Mart. They asked me if I had any money. I told them no. So fast forward to about 30 minutes to an hour at most. I come back and there they are again. I get out of the car and again they ask me if I have any money. Which I say no and wanted to mention that they already asked me but I decided against it. So I wonder how many people truly need help?
