Learning: does the fireman bug you at all about not drinking with him?
In my dating misadventures I haven't encountered any issues.
When I get asked why I don't drink I just say I hate hangovers, It ruins my metabolism and I get insomnia.
If anyone says just have a couple drinks; I just say I've never been good at that- its 0 or 10.
Many times the guys have said it was actually really nice not to have an alcohol date.
