Baby mama drama....how is this even MY problem?

Welp, some things should just come natural but they can be hard--like telling people to call BEFORE they come to your home..When you send your letter you should call her and tell her that from now on she is to call you BEFORE she comes to your home, if you wanna be nice you can say I am often not dressed for company or I wanna make sure the house is clean or something like that BUT I wouldnt i would just leave it at she best call first.
