I have a person in my family who does "..." typing for 15 seconds to 5 minutes just to say "Okay, if you're busy, I'm going to the grocery store".

I didn't need that information.

You just sit there looking at "..." for an indeterminate amount of time not knowing if you can move on.

Frustrating.

And yet I'll miss this frustration so much someday and I never allow myself to forget this fact.
