Here's one of mine that still embarrasses me now.....
When i was 19 i embarked upon a health and social care course, the tutor gave us a question sheet to fill in, so i started off with the first question that said, 'write your name'
so i did, the next question was date of birth which i happily added, the third asked a question about the amount of siblings i had, then the questions got weird, one of the questions stated to stand up and say hi to everyone, which i did, then another stated to stand and count to 10, by now i was looking around and wondering why no one else was doing it, i thought to myself don't be such a wuss just do it, so i did.....i got all the way to question 10 that said 'now you've read through the questions would you please only answer the first one

Well i had a mixture of embarrassment and humiliation, the worse bit was that the tutor kept saying to me "well done" after i'd answered a question so he was encouraging me and like a twat i took the bait......safe to say i never went to that class again
Even when i think about it now the embarrassment and humiliation is still there
