When my parents get the glasses all down for me to set the table with. Okay, I realize that they built the kitchen for people who are over 5' tall, not under, and they really do want to help, but saying, "Oh, let me do it," when I've almost got the glass really cheeses me off. If I need to get a fork to nudge the glass out a bit, I will, but I assure you, I can reach it.
Also, all the people at church who offer me a ride home...after I've called my parents to come get me (I don't have my license yet). I appreciate the thought, folks, but outside when my mom's 5 minutes away from the church is not the right time for that. *facepalm*
