How do you react when people try to convert you?

This evening the mom of one of my boy’s friends dropped him off for a spendy and brought a pamphlet for her church. She spent a while explaining how much I would like the pastor and how great his sermons are. I am very happy with my faith and I am done searching. I so wanted to hand her a pamphlet of my own, or tell her that I am just plain not interested in attending her church. Both of those options felt rude so I smiled and said thank you. Whether you have a faith you follow strongly or are a devout atheist, I am interested to hear how you react to attempts to convert you.
