Mother's Day is not an easy time for an exorcist.
You either go over to her place and listen to her mumble strange slavic syllables at an even stranger slavic radio broadcast.
Or you have to go through that, "She's in here with us, Karras!!" crap that Captain Howdy is constantly ranting about.
"Deemeee, what for you do theees to meeee?!!!"
Either way, Mother's Day is a drag in this racket.
