When you convert to Catholicism at 17, you miss out on a lot of those fun "first communion" things. I had a very special, very beautiful, ceremony though, with only 2 other people being confirmed/ taking eucharist. It was easter vigil...beautiful. I didn't get to wear the big white gown, but they gave me a beautiful little orchid to wear...i saved it
Edit: It's been a big long while since there's been a family wedding (dads or moms), but I don't remember a "dollar dance" but I remember something similar to a circle dance...where women are on the inside, men on the outside (or vice versa), and the music plays, and the lines bow to eachother, dance side by side (similar to polka), and then the two circles move in opposite directions until the music stops again, bow, music, dance. It goes on for quite a while, but you get to introduce yourself to a ton of people and the bride gets to make her rounds as does the groom.
