The best way to stay in contact with unloved ones, such as ex-girlfriend, ex-boyfriend, ex-wife, ex-husband, ex-spouse, ex-partner, ex-fuckbuddy, ex-relative and all other least favorite people. Collect calls are the most expensive option for calling, so use a payphone and dial 0 to show your ex-loved one how much you care.
Yo! I made a collect call to my ex from jail and the phone company banged her $30! Revenge ain't cheap!
