> Sure, but the interruption was for a good reason and my help was actually needed. Wouldn't this be true of just about everyone complaining about such interruptions though? I can't imagine anyone would mind being interrupted if the building were on fire. People just differ on what they consider to be good reasons. I'm sure there are unreasonable people on all sides, both those asking for unreasonable conditions to interrupt them and those not respecting reasonable conditions for interruptions, but I don't think it's the majority of the people complaining about it. I've been in this situation a few times, and lots of people just don't have good impulse control and so don't even think twice about interrupting you if it's more convenient for them.
