Sure, dating 18yo is fuckin weird, but on the other hand, if your date (of whatever age) doesn’t drink and you suddenly realize you have no date ideas that don’t involve drinking, you may also need a moment of self reflection.
Not sure why down voted it’s a valid point even if they don’t drink and ignoring I wouldn’t date someone in that age group. I don’t want to limit locations for a date or hang out.
Personally I probably wouldn’t date anyone who doesn’t drink either but that’s my own preference.
