I survived the weekend, and no one got into any fights. We have one more gathering tomorrow, and with various non-relatives that will be there, I'm pretty sure we'll all be on our best behavior.
Things I learned at my half-brother's baptism:
1) The Holy Ghost's method of communication is equivalent to, or at least comparible to, dropping a nail onto a chalk board tray. If you're making fun of the object lesson with your older sister, you won't be able to hear the Holy Ghost.
2) When you have 2 voices talking to you--one telling you to obey your mother and go inside, and the other telling you to keep playing because it's fun--the one telling you to obey is the Holy Ghost. I thought, at first, that it was fear of beatings by said mother, but I was wrong.
3) The Holy Ghost will help us to choose the right. Without it, we're pretty much incapable of making good decisions.
That's all I learned. I wish I'd paid more attention...
