I'm a male and work out of my house so I'm usually the one who takes my son to pre-school. A few times I've been "invited for coffee" by pre-school moms. I'm not sure if that is actually getting hit on but it feels close. I don't know if they are married or divorced but they certainly know I'm married since my wife drops him off as well. If I was a single dad it would certainly be a better meeting place then at a bar.
