The following is a synopsis of Elaine's data gathering:
1) no words exchanged
2) no ring on finger (from where she was sitting)
3) drives a black Honda Civic (so I'm pretty sure I'm either color-blind or the worst detective ever) Elaine jotted down the license plate #, but that's a little too stalker-ish for me.
4) we now know that he arrives on Sundays at around 6 (2 Sundays in a row is a trend, right?)
Assuming the rain stops by this afternoon, dog park at 6pm it is.
