As t’is the season if you’re out at a party and someone says they don’t drink, don’t ask why. Not because it’s intrusive, but because IT WON’T BE A FUN STORY TO GET THE PARTY STARTED.
Most of the time the reasons broadly fall into
1. “don’t like/Religious reasons”
2. “I didn’t want to die/nearly killed someone”
3. “I wanted my kids back”
It’s just not worth the social hit to the mood
