Sure, we all hope that our parents have happy relationships especially after a difficult divorce, but there are some boundaries that just shouldn't be broken. While they say "love is blind" and "age is just a number," if your parent chooses to be with someone who is younger than their adult child, things can get seriously awkward. Do you even bother to call someone your step parent if they were five grades below you in school? Or, do you just never give your parent's new partner a title and avoid all eye contact at holidays while doing the math that you were in high school before they were in kindergarten? Of course, love can sneak up on anyone, but there is only so much wine-chugging in silence that can occur before you have to address the fact that you could've babysat your own stepdad in middle school.
