Do you correct people?

I will only correct someone if I am alone with them. If there are other people present, or even someone within earshot, I refrain from making a comment. People can get embarrassed if the are shown to be wrong, so I avoid embarrassment. I know this because one of my friends had a habit of correcting people when there were large groups, and it was always embarrassing.

I do make mistakes of my own sometimes, though. Some words, I've never heard someone speak, but I've read them in books, or I may come across a word I've never seen before, and read it out loud phonetically. I don't see how a person can speak perfectly all the time without being corrected, so I don't think it's wrong to correct someone, just some wrong instances.

Jam it back in, in the dark.
