Me: Do you want to come for a visit while my sister (your daughter) is here, before she moves halfway across the country?
Dad (2 days later): Got ur email today.
Me (9 days later): I was thinking there would be more of a response. Did you want to come on Monday?
That’s right, no response. No visit. Is it that hard to say, sorry, can’t make it? I wish he’d just respond.
