What is this "dating someone" that you speak of?
Dating isn't just what couples do, it's what 2 people do to get to know eachother and decide if they're compatible with one another and work well or not, and just have fun together. And if they're not compatible, it's still a fun thing to do! So sure, if I get asked out on a date then I'll say yeah if I'm single, and the guy's at least semi-dateable. Something might be there and something might not, but it's always worth a shot in life. Can find love in the oddest of places. And if you don't find love, might find a really close friend! I'd be happy with either result.
So as long as the guy or girl knows that it's just two friends on a date, and this is not just me saying yes to actually being in a relationship with them, then it's all good.
Also, if it's a free meal, I'm there!
