Every activity I listed above qualifies as sufficiently date-like (but not necessarily so, at the same time). Like I said, you don't have to be desperately creepy about it. Make it sound nonchalant, if that makes you more comfortable. Hang out for a bit. Talk (because you're spending time together). Boom, that satisfies the requirements set forth by Dave. And, if you two hit it off, you can make it a habit to spend time with each other.
