i used to answer honestly like because this and i never understood; and still don't (i'm on the spectrum); why some people got angry/frustrated and it almost always eventually germinated into a full blown fire-this-asshole-already movement in the places i worked at until my therapist made me aware that people don't really expect a true answer and will only accept certain responses.

i call it the social handshake now and i allot an extra 10 minutes every single time i schedule a work meeting an wait to hear certain key words/phrases before continuing on for the actual reason why i scheduled the meeting. lol

I always answer "well I'm still here" and let them make of it what they want.
