You introduced yourself in the elevator. I thought you were cute, got flustered, and made an awkward joke about living on opposite sides of the building (so make as much noise as you want- party time!). What I should have said was "Welcome to the neighbourhood. If you need any recommendations I'd be happy to share." and opened the door to have an actual conversation. Since I missed that opportunity, I took to the "I Saw Yous" to see if maybe you would be interested in a real conversation. Surprisingly, it seemed like a less embarrassing way to find this out than in person.
