The funny thing about being one of a couple of aging ravers is that embarassing conversations like this happen with increasing frequency:

A: …And then there was that trick you did the night we first hooked up, where I asked for a sip of water and instead of handing me the bottle, you took a swig and then gave me a watery kiss!
A: I don’t remember that.
A: Er, wasn’t it you that did that?
A: Uh, yeah, I think I’ve done that. But I don’t think I did it the night we hoooked up.
A: But wasn’t it you that taught me that trick? Or did I teach you?
A: Can’t remember.
A: Huh.
