I'm a widowed mom of 3 kids, planning on moving to Queretaro in a few months. I know there are a lot of cultural differences, so I realize I can't act like a preachy person who knows what is best for everyone...but I would be super surprised in a room full of all women if they were all really OK with a man telling them to smile. I don't know if I find it "offensive" but it makes me feel a little like punching them in their ass. I'm not 5, don't tell me to smile, motherf***er, haha.
