Bugged out

My sister stole my exterminator appointment today. She totally did. I usually have them come over once a month to spray the apartment and the hallway, just to be on the safe side. Bug man was supposed to stop by today and he had promised to call me before heading over. But nobody called and nobody came over.

Unsuspectingly I talked to my sister on the phone later in the day and she said: "It's funny because the exterminator called out of the blue and said he was on his way, so I told him to 'come on over' and he just sprayed our place."

Huh?? He meant to call ME. They were supposed to come to MY place. Obviously they called her by mistake, since we have the same last name and since she's in their database as well, and she just went along with it. Not cool. She's probably joyously skipping about her living room right now, feeling safe.
