Long history with the MIL.. she used to live with us for years while the kiddos were little and it became a little too much for us to be under the same roof. She finally moved out last year about 10mins away. Because she lives so close, she comes over unannounced several times a week to pick up mail or give some treats to the kids. 

Today I got home early from a shitty day at work and was alone in the house. I then hear the gate open. 

I knew it was my MIL because she NEVER rings the door bell. She knocks on the door, “Open Up, it’s Mom”  

I swear I duck low to the ground behind the couch and away from windows. You’d think I was hiding from a sniper. 

She goes around and knocks on the back door and I don’t move or make a peep.  After 15 mins or so, she finally leaves

My husband comes home an hour later and I ask him if his mom told him she was coming by. He said no. He calls her later and I could overhear the convo. She asks if he was home because my car was in the driveway and he says no he was at work. She asks a few more questions but I can feel in her voice that she knew I was home.  My husband asks if I heard the doorbell and I said “no (it was true) I must have been in the bathroom.”
