Embarrassing childhood moments

Mine was when I was 10 and at a holiday camp. I was going for a shower at the facilities block and there were none free.
So one lady had joked with her son that he could take a bath in the sink in the laundry room. I had no idea she was joking so took a bath in that. Wow, I thought it was quiet but in walked a woman with her son whilst I was having the bath, they took one look and laughed and just carried on with their laundry. The kid walked over to the sink and pulled the plug out, I was like "hey kid, what are you doing".
