Re: Things people say that irritate you
"I'd like to...." (such as "I'd like to thank") - if you would like to do so, then just do it, instead of saying you want to (i.e. say "Thank you" instead of "I'd like to thank you.")
It's not a huge deal, unless I find myself saying it, in which case I wonder why I have to resort to something like that.
Also the phrase "past history" is a bit of a pet peeve as well.
