Perhaps other people are right sometimes
This past Shabbat I was at services. Person x said "[The Knitter of Shiny Things] should lead kabbalat Shabbat because I like it when she leads... I hope you don't mind me volunteering you. I'm going to continue to volunteer you every week."
Me: I'm happy to lead kabbalat Shabbat or ma'ariv, but I don't want to lead both of them. Maybe I should do ma'ariv, though, since I've been doing kabbalat Shabbat a lot.
(I actually did want to do ma'ariv in this case)
Person Y: I volunteered to do ma'ariv if we need me to, but I'd rather not lead anything.
Person Z: I can lead kabbalat Shabbat.
So we ended up with person Z leading kabbalat Shabbat, me leading ma'ariv, and person Y not leading anything (and person x not leading anything as well). My thought was that even though I think I'm good at leading kabbalat shabbat, perhaps others want to lead it and should have the chance to do so.
Except that person Z lacked energy, and there was this whole Lecha Dodi fiasco where they used tune A for the first half, switched to tune B which actually has 3 different tunes in it, and then in the middle of tune B, since they must not have known all of it, instead of doing tune B1, tune B2, tune B3 and tune B2 again they did B1, A, A, and B2. (i.e. as they switched back to the original tune they were using for the first half of Lecha Dodi, except for the last verse.) Which threw people off a bit. Also they sang in a high range which was really hard for the rest of us to sing in.
Then I led ma'ariv and did a fine job of it. (Though at the end of Yigdal I really needed a drink of water and I was having trouble singing it without coughing.)
But had we followed person x, I would have led kabbalat shabbat and done a fine job of it, and person z would have led ma'ariv and also have done a fine job of it.
I'm not saying that I'm the best person in the world at leading kabbalat Shabbat. I'm not even saying that I'm the best in the community. And there are other people around here (who are also J-bloggers and are probably reading this post and know who they are) who are good at leading kabbalat Shabbat. (They were not present this weekend.) They would lead it with less singing than I do, but they would sing most things. (Actually, person z did a lot of lai lais, which is something I normally *don't* do, unless the congregation is really pushing for it. Person z was the one who was instigating the lai lais. Lai lais are fine when people have energy, but if they don't, lai lais can be pretty darn painful.) As far as I'm concerned, both of them are equally good at leading kabbalat shabbat as I am. I just like to lead it more than at least one of them does, so I usually end up doing it if it's the three of us.
But there are some times when people lead and I think "I could do better than them!" And since there's no way of knowing ahead of time who these people are, perhaps I should lead kabbalat shabbat whenever the people who I know are good at leading it aren't there. And I don't go there every week, which means I'm not leading every week. I just feel like I might be doing the same thing to others that annoys me when people do it to me. But better that than sad kabbalat shabbat, right?
So after services I told person x that I saw the wisdom in her ways.
