Something lighthearted I think conveys the best message. Example (which won't exactly apply, coming up with it on the fly)
This is Wally Stevens, we met a few months ago at Event Y chatting about law school and all its shenanegians. I'd love to pick your brain some more on law school to hear from someone who's been through it already - could I buy you a cup of coffee sometime this week and ask you a few questions?
Hope to hear from you,
I took the line from the guy from the previous post.
This thread is ironic because last night in the bar I went around introducing myself to everyone just for fun. Course it could have had something to do with the eight Yuenglings, but hey! networking! (Not the best impression was made I'm sure)
