BEFORE YOU FRIEND 
I will not be refriending certain ex-friends, mine or those of the people I'm close to. They're ex-friends for a reason.
I don't talk much until I'm very comfortable with people, usually I may just interject with funny things if my friends are talking. If we've had more than one nice interaction in the past and have mutual friends, I'm probably waiting for a good moment to friend you but haven't yet bc I'm awkward or find you intimidating ðŸ˜
Friends of friends may friend me if we've interacted and/or you've read up on our boundaries.
I don't accept random friend requests from strangers. We have to have at least interacted enough for me to consider you an acquaintance before I even consider it
I don't friend roleplayers most of the time due to them not understanding boundaries or what systems are. No, I don't want to ship my skin with you. It's most likely one of my alters' skins or a "me" skin. Most of my alters aren't comfortable with ships involving them, often being uncomfortable with specific ships depending on who's fronting.
I have no age requirements for friends (other than like... just not wanting to int with kids below 13 bc why are you talking to strangers please be safe on the internet for the love of god), just don't be weird to me, my gf, or my friends please. That being said, I am an adult. I only say my exact age to friends I trust because a (now ex)friend of a friend called me a pedophile for sitting with my online kid on safe server.
