@_ThatOneStanGirl_ Same. I'd also have no problem with John, but then again if Sherlock was my uncle that would make John my uncle as well cause they're married :) and if Sherlock was my uncle, that would kinda make Mycroft my uncle too cause they're brothers, which would also make Greg my uncle because he's married to Mycroft.
Woah. All the dudes from Sherlock would be my uncles, and I'd be loving life.
