I found out yesterday that one of my best friends has been a Christian since June. Not one of those crazy right wing Bush voting Christians, but it was still a bit of a shock.
You've started a journal, hooray! That IS strange. I guess that I don't so much think that it's strange that you have a best friend who's a Christian, but that you didn't know until now and they've been a Christian since June. Seems like he/she'd want to tell you about it, not in a saving your soul kind of way, just in a "oh hey, I've made a major decision" kind of way. Good luck with that.
