Tiny amount of background.
I'm early 20's, moved away from home at 17, I haven't lived within 100 miles of my hometown since then. Occasionally, DH and I will travel four or so hours to visit his family, and we don't drive so we almost always get a coach (no prizes for guessing where I am right now!).
If I mention to either of my (divorced) parents, they'll request that I text them when I get there. They don't always know that I'm going, and obviously they don't know when I go out, or go to stay with friends, so I find it odd that they ask for a text on these occasions.
It's a small thing to remember, but I do get snapped at when I forget, which in the mess of getting into the house and dumping bags/hugging in laws etc, I often do.
It's such a minor thing in the scheme of things, but AIBU to think this a little strange? Do you do this with your adult kids?
Just to clarify completely, I don't live at home, I haven't for years now, so they rarely know my whereabouts anyway.
