If your kids have extracurriculars, do you and your SO share duties...?
My 14yo and 18yo both have a lot of extracurricular things they're involved in - sports, clubs, etc. - and while the 18yo is living on her own and drives herself around, my 14yo still needs to be driven places. Anyway, even though my husband is technically available more often than I am to do so, I'm the one who ends up taking her to and from wherever... EVERY time. Does your SO make you drive the kids around all the time, too, or does he share the role and do some of the driving sometimes?
Some beach, somewhere
There's a big umbrella casting shade over an empty chair...
