Dear guy behind me in line at the grocery store,

You are probably right, that I should have noticed you only had one thing and let you check out in front of me. I wasn't thinking. However, that does NOT make it appropriate for you to accuse me of "helping my kind" by "letting the woman in front of me go." I didn't let her go -- she actually was in line first. Just like I was in line in front of you.

A couple suggestions. If you don't want to wait in line to pay for your one thing, do a better job making a list next time you go grocery shopping, and avoid the subsequent one-item trip. Also, leave the race card out of things. We're all the same "kind." Jerk.
