I feel the same way.
Who does this? Who just drops by?
not terrible, lots of people feel that way. I have about three friends i would be OK with just dropping by, the rest need to call ahead!
Why do you feel bad? Is it a mess or cluttered or are you too self-critical? If someone is coming to your home they want to see you.
I'm not OP but i am a big introvert and i need to prepare myself for visitors (most of them. my BFF can charge right in whenever she wants). if you show up unannounced don't expect me to be making a lot of conversation.
who is coming by unannounced in these times?
I feel like phoning someone unannounced is intrusive. I can’t imagine just showing up on someone’s doorstep!
This is why my IL's no longer "Drop by." Let's just say it wasn't pretty when they tried this the first time.
