How Did Your Parents Embarrass You?

In honor of my step-daughter's birthday comes today's blog idea... Madison is 15 today, and I'm sure she'd happily tell you about all the things her mom does that just bring shame and humiliation to her.  Maybe her mom asked her a question in front of her friends that made them giggle at her (like "Did you remember to pack clean undies?").  Maybe it was something she did or the way she did it.  Thinking back over your lifetime, was there ever something that your parents did which really, really embarrassed you at the time?  What was it?  Why did it upset you so much?  Can you look back on it now with a different perspective?
