Another guitarist asks you to jam. What do you, personally, start playing?

A djembe/cajone players asks you to jam. What do you play?
I always ask what key, but if they just say whatever, I'll play in C.

Feelin' Alright by Joe cocker (dave mason actually) is a good one to jam with and simple
with a guitar player, i just say, in the key of *insert letter* *insert scale name*

do not go on guitar forums

there are drugs there

( and ololol there are )
I generally ask/discuss what key to play in, then I'll just start playing in the agreed key.

I don't usually go in keys like F#, C#, Cb, or Gb, but that's just me.

Big Bach is listening you!
I just play what I feel like, and strangely we end up sounding very good together.
