generally i like to give a dollar or two if i have it to the homeless on the corner so on my way to walmart a guy on the corner holding a sign wearing a dirty shirt and has a dog so its a red light i give him $2 i dont care what he spends his money on or if hes a scam artist because usually im not around after they leave to watch them. but after walmart we stopped at the gas station i see the guy cross the street thinking hes coming in the store for snacks.turns out he walks to lexus changes into a dress shirt and tie and drives off.now im like look i know it was only a few dollars but im kinda mad im pregnant and could have bought a greasy gas station hamburger.
