backseat friend

The one that is always just there, they get invited but they are more of an extra in the background or… in the backseat. Mutually known but gets left out, doesn’t really know why they tag along.

There is a duo in this trio, why am I even here I am just the backseat friend.

I like hanging out with them, they keep each other entertained and I just get to stare at a tree or something, the backseat friend :)
