It does seem ew but I totally understand her. My bsf is 2 years younger than me but when I think about how she's turning 18, it feels weird. I've known her since she was 12 and saw her at her best and at her worst that I felt like I was her own mum (?) it's not easy to explain that kind of this but sometimes even when the person is a month younger than you, you can't help but feel like a parent in certain situations
Dunno, sometimes using the "kid" word looks more like putting a wall between them, nothing else. I do not feel bothered by it.
In fact, I usually do not feel bothered since it is a fictional story, thought it could be possible irl.
Ma'am stop. Stop referring to the guy your sleeping with as a kid for one cause eww. And wtf would you apologise for saying that mid devil's tango. Also he wants to be with you! Ahhh!
