When you tell someone you'll do something "ASAP", do you really mean "ASAP as long as it doesn't interfere with my life too much"?

reading this makes me feel like i told someone i would do something asap but didnt end up doing it. i wonder what it was

I do mean it when I say it will be done ASAP, I also ask them what their time-frame is.  If it is doable I will get it done, if not I tell them - period.  No sense in pissing someone off do to a misunderstanding and crushed expectations.  In most cases I also send them and the affected teams an email stating the deliverable and the time frame. 

If it is personal not business sames rules apply
