How do you sit as a visitor? Perso: It depends at whose house I am

Probably a 3 if I'm being honest with myself.

7 until a more comfortable chair is ready

As a visitor? I'll sit awkwardly in position 1.
At home? Literally all of them.

1 2 3 5

a lot of these can break a recliner, so most i don't do. Normally 1 unless it's a friend I really know or have a girl w/ me and she needs a place to sit. I'll change positions so the chair doesn't break cuz I've had that happen to my chair and it wasn't fun. I mean, it was cute they were so comfy w/ ea other, but my chair disagreed.

This is 100% dependent on whose house it is. I am not going to go 3, or 5-9 at some friend of a friend of friends house. 5-9 are reserved for close family and best friends.

as someone with ADHD.... my answer is yes.

All of the above
