TIFU: By being late to my gf's special dinner

This happened last night. So, the gf has been planning a special dinner for a couple of weeks now for her brother, mom, and myself. It so happens last night was my coworkers last day at the company and naturally, I attended her happy hour after work. Well... a couple of drinks and shots pass by and I realize I'm late for dinner.

I show up late, drunk, and missing a couple of things she asked me to bring. To say the least, she was pissed. To top it off, right after dinner I go crash in bed until this morning.

TL:DR : Gf has special dinner with family planned, I show up late and drunk because of a hh.
