Girl wants to meet for drinks but... I don't really drink WHAT SHOULD I DO?

I asked my wife out for a beer on a hot day when I first met her. She told me she doesn't like beer. I should have turned an ran but I didn't. She's not into cars either. Another strike! Sex, she's not into that either. 3rd strike. Aw what the heck. We've been married for 29 years and pretty happy. You never know where a meeting might lead. Just be yourself, drink a beer or a drink and follow up with water like many suggested. Nothing wrong with that. You two already have something in common that may not involve drinking. Go for it!
