yes that is disturbing. i intend to be no younger than 25, maybe older. i also get freaked out when i hear about people i know getting married though fortunately nobody i know well has done it yet.
though going to a wedding would be fun, actually.
Luckily nobody I know within reasonable travelling distance has got married yet. One of my really good friends who used to live here and is now in Georgia is getting married in December, and luckily the distance means I dodge having to go. I think I'm just not a ceremonies person.
Plus it would feel kind of dodgy sitting there thinking "I give this five years at most".
