Have you ever done or said something then been embarred about it?

No its not stupid, i feel the same way sometimes aswell. I get embarissed by saying things in front of my family and then thinking it was stupid later. It could be that you have been told a lot that what you have said or done is silly an that you should be embarissed about it maybe? i dunno but for me its because my family put me down a lot when i was growing up and laughed at me for little things. Dont worry about it, i tend not to care anymore, people feel like this aswell all the time.
