I'm not really thrilled about living under the same roof as my mother either lol :)
10 minutes before my mother died, she called our house to wish my wife a happy birthday even though it was two days before her birthday. I was busy getting my drag boat ready for the next race (which was two days away) and I didn't stop what I was doing to say hello to her that night, she died 10 minutes later, and till this day, it haunts me. Call your mother and tell her you love her
