all the time! i am often chewing off my tongue as i practice self restraint
Thsats why I have thsese tellible thpeech defectth...
Seriously though....sometimes you just have to blow off some steam. I never fill in the to: or the cc: on an email until I've reveiwed the email several times, and very often have to delete out text. Occasionally I'll write an email and save it and then go back later to make sure the acid isn't too corrosive
before I send it.
Same thing happens on the forums, only rarely.
More often the mere act of typing triggers questions and clues to research, and before posting I'll investigate those thoughts and figure something out or realize I was wrong and then need to delete it.
