Those smells

I have to take a break...I am chopping red onions to make a North Indian style chili in the slow cooker tomorrow(like a curry type dish over rice, have to grate some ginger too). Those onions make my eyes water like crazy!
What is it w/ homeless men and that smell? I went to Target today to get my ingredients and there is a bench near the door and I wanted to sit there to wait for my ride. There was a homeless(?) man w/o legs sitting on the bench w/ his wheelchair next to him. I couldn't get within 10 feet of the bench b/c the smell was so terrible! I wanted to go back in and buy him some deodorant ...do they not have showers at homeless shelters...maybe not, maybe its a security risk? My town does not have public transportation so I was thinking, how does a guy with no legs get to Target? Back to cutting onions...
