Funny story from my reunion that I didn't attend. Official event by senior class officers: It was planned in a private room (top floor really) of a bar (that also served food) and was $65/ticket. There was an optional party bus for the clubbing district afterwards. A lot of people were offended/angry at the cost. The facebook page was interesting.
So a couple of people got together and put on an alternative reunion event. It was a family friendly bbq/potluck in a park. They started their facebook page with "now that we all have children and responsibilities, we can't party like we used to..." which was a huge slam on the other event. And I laughed because I knew those girls and 1. they never partied in high school and 2. they really thought that by that point the majority of people had kids which a quick glance at facebook profiles disproved.
To their credit the senior class officers were really gracious about the whole thing. Juding from photos, a lot of people attended both.
And yes I remember during senior class elections the reunion thing being mentioned. Though it does seem weird to hold people to vague promises made at 17.
My siblings are class of 03 and their senior class president is someone we've known since he was a toddler. He's never been good at organization. He didn't even book somewhere for the reunion. The plan is "everyone show up at the same extremely popular and crowded bar and hangout on this one night". That should go well.
