public fasts, liturgy, and obligations
Another problem created: I need to make sure I'm familiar enough with the insertions into the liturgy for public fast days to be able to lead them next week. Either that or get David to lead that part. (I know we insert Avinu Malkeinu after the Amidah; I can't remember if there are other changes. Fortunately, I own a copy of the siddur we use, so there shouldn't be any surprises.)
I happened to glance at next month on the calendar and noticed that the fast of the first-born (before Pesach) also falls on a Thursday, my day to lead services. This one poses more uncertainty -- it's a public fast day but only for some people. Breakfast will be held, taking advantage of a rather dubious rules hack, but I don't know what liturgical changes are implied for a day on which some people must fast and others not. Fortunately, I have a month to find out. :-)
There are five minor fasts in the calendar. Three have to do with the destruction of the temple and one falls before Purim (commemorating Esther's call for a fast before she tried to save her people). These apply to everyone, but they don't resonate for me at all. I can't say exactly why, at least in the case of Purim. Maybe it's this nagging question of why this attempt to wipe out the Jewish people in a particular area warrants special treatment when it's not a singleton -- just the first that the rabbis noted. I don't know; I haven't spent a lot of time thinking about it.
But the fifth of these minor fasts is the fast of the first-born on the day before Pesach (or earlier if that would cause it to interfere with Shabbat, like this year). This fast exists because of the tenth plague, the one that killed the first-born malees. Jewish first-born were spared but this is later given as a reason that first-born men belong to the temple for service to God. (There is a redmption mechanism, called pidyan ha-ben -- which is good because otherwise those people would be stuck today.) And of all the minor fasts, this one resonates for me. Isn't that odd? I'm a first-born woman whose ancestors were never endangered by this plague, though obviously had I been there I would have been.
I'm a woman, so traditional Judaism would say I'm not obligated. But a consequence of being egalitarian is that I don't get out of it that easily; if I believe men are obligated, then I am obligated too.
I don't know if we are obligated, but I should give this one more thought. I've tended to non-observance in the past, or going along with that rules hack I mentioned, but I'm beginning to think that the correct thing for me is to (1) keep the fast and (2) not use the rules hack. I've got a month to figure that out, too.

I believe I've seen you mention it before, but I'll admit that I required the refresher to know what you were talking about. :-)
