My first wasp sting - OUCH

On Father's Day we went swimming at my mom's house and I experienced my very first wasp sting. NOT fun at all. I didn't know what had happened until I saw the stinger sitting in my arm and it started burning like crazy. It's now 2 days later and my arm still looks like this! I kind of feel guilty but once we got home I totally decemated the wasp nest on our front porch. They'd left us alone so I was planning to leave them alone, but after being stung I didn't want one to get Ezra b/c I now know how bad it hurts, or am I just a wimp? :)
