am i ashamed?

I've noticed a recent trend in the way I approach non-Mormons. I think it's called shame.

I feel reluctant to be so cavalier about sharing my faith. I feel... I feel like I've been bitten one too many times. It feels like... It feels like unless the sharing of the gospel message is solicited, it feels forced down someone's throat. So I don't do it. When I see other members talk to people who aren't members and it's uninvited, I feel sick. I feel embarrassed.

There, I said it. I feel embarrassed.

So there it is. Now what?
