@kate just to be pedantic, the second person may not be trans - or maybe you know them?
I know a couple personally where the husband transitioned, for a while I think their marriage became null and void until gay marriage became legal. Anyway AFAIK they're still happily married - I guess I wonder if the pictured people are a couple, one of whom transitioned, and the second sign is specifically about the change also having been beautiful for the partner.
Probably not lol, but was a nice memory!
