I don't really know the difference between a bee and wasp, but I just stepped on one! It hurts! I was going outside after I'd put the kids to bed to read and enjoy some potato chips and the cool dusk air and my first step onto the deck was a very painful one. I knew I'd just stepped on a bee. I bounced back inside, fluttering in pain, dropping my book and managing to save the chips. I looked down and there was the guilty insect, walking around on my welcome mat, with a string of nasty yellow-ish ooze following it out of what used to be his stinger spot. I pulled the stinger out of my foot and researched home remedies to soothe the pain. Right now, I've got toothpaste on the bottom of my foot. It took the edge off, but it still hurts.
It'll take more than that to convince me to wear shoes when I go outside, though. :D
