Putting my life on the line with A7o

I thought this was a good call on my part.

BB 4550 chips

blinds 150/300

UTG folds
Button pushes
Hero calls

There are three reasons why I think this was a good call. First reason is the Button's action on previous hands. Second reason is UTG's action on previous hands. Third reason is BB's action on previous hands. In other words, I am not talking about the situation, but actions I had actually noticed on the part of the three others. Care to guess what these actions were?

BTW, this dialogue occurred after the button busted out with KQ.

Button: A7?
Hero: You were short-stacked.
Button: So were you.
Hero: Yes, with A7.
