you know you are a pushover when:

you know whats annoying?

when this person you are friends with is doing something a little cheap and you know it and the person knows you know it but neither of you are talking about it.

and then one day outa nowhere the person goes " its really your fault you know that i am doing this"

mouth open,wide,gaping you go "why is that"

and the person says "well cos you knew of it in the first place and you never told me and now i cant stop"

and you go "oh well yeah.sorry"

thats when you know you are a push over.
