Anyone else have a friend they model their behavior after?

Hello!!

I have a friend who's a lot better socially than I am, and they help me with my social skills.

I'm not sure if this is just a teen thing (I'm 17) but I tend to model my social behavior after them and think about what they would do or say in that situation or what they'd say to me if I said or did a specific thing in a social interaction.

They are my only role model for this and I've known them since middle school. Their feedback has been genuinely helpful and they always take time to explain things to me and make sure I understand what they're trying to say. They are aware and accepting of how I am too and understand my needs. I'm really grateful for them.

Does anyone else have a friend like this?
