Text: laying in bed after a long long day of work, travel, and many drinks, my fiance and i were laughing and having a good time. my ex came up in conversation (as a story of something funny that once happened in our friend group). my ex is extremely irish and it reminded me of a client i saw earlier in the day.

i was really excited to tell my fiance, " this client i met today moved here last year from ireland! his name is declan! i love that name, don't you," and we both kept saying the name ( for the sake of future children, middle names, that sort of thing ya know). then i paired declan with my exes extremely irish last name instead of my fiances extremely croatian last name. oops.

TIFU by accidentally saying my exes last name.
