Say something to your grandmother!

About 2 weeks after my Grandma Sizelove died, my this awkward moment took place:

My mother and I sitting on the couch:

Mom: looks at the bookcase where my grandmother's ashes are in a box (thats right a box, & even better we forgot to order an urn from the funeral home, so @ mass she was in a box.)
Mom: I've never felt so close to my mom in my whole life.
I sit here and talk to her everyday. I tell her everything.
Say something to your grandmother, Lisa.
Me: Uh, mom, I think thats kinda wierd.
Mom: SAY SOMETHING TO YOUR GRANDMOTHER! (yelling)
Lisa: Thanks for dying when I was unemployed, so I didnt need to take off work?!
Mom: Screams, Oh your horrible! HORRIBLE!
