Communicating with people is hard, especially when it comes to your co-parent. But it doesn’t have to be this hard (see above, yes, a real text from my co-parent who was upset with me because he read our child’s schedule incorrectly and somehow also missed the school’s multiple messages about the event as well).
Rule #1: Be nice.
Rule #2: Put your kids first.
Rule #3: Don’t say/text/email stuff you may regret later.
Rule #4: Take responsibility, seek resolution, not blame.
