Amen, Robvia. I love my wife very much, but she gets very frustrated, bored and annoyed very quickly at parks. The first time I went to SFMM, she got sick and I had to sit with her for 2 hours doing nothing when there was nobody in the park. And I rarely stay at a park until closing anymore, because I can't stand the guilt. Usually I leave by 5 p.m. and take her out to dinner or something to make up for the horrible day she just had.
On the other hand, if I leave her at home, I feel guilty too, because she'd be bored. It's a Catch-22.
