Meeting the Parents

[Isonyx]

So I've been persuaded by my girlfriend to meet her parents.
Her father already dislikes me. There were two incidents, one where he found some condoms in her drawer and another where he felt I was negatively affecting her grades.

I'm supposed to go over and meet the parents tomorrow.

I want to make a good influence on her father, but I'm already on bad ground due to him finding the condoms.

Anyone have any advice on not getting punched in the face when I go over for a visit?

(I already told him that though the condoms were mine, we weren't using them. I don't think he believes me)
