When I was younger (like 12/13 and younger) my older cousin (like 20s) always pecked me on my lips goodbye (no one else did this in my family) and I always felt really uncomfortable but no one ever said anything so i went along with it.
He’s a lovely guy but I ended up avoiding him and staying in my room when he came by because I hated it, and I was wondering if its a common thing in your family as I’ve heard it’s a thing?
