Kinda friendly home game?

I have been playing at this "home game" the last couple of weeks. I am a friend of a friend that runs the game, so it's kinda friendly.
Anyhow, I was in a hand where I was trying to make up my mind either to fold or go all in. And a guy who was not in the hand said he would have to call time on me. So I went all in, and got beat. Of couse I think why did I let someone not in the hand influence my decision?
