grandma great

As we were laying in bed tonight Luke and I had this conversation:

Luke: how old is grandma great?
Mom: 89.
L: that's in the 80's, right?!
M: yes buddy.
L: that's REALLY close to 100!
M: yep.
L: she is REALLY lucky to be that old. how come i can't be that old?
M: maybe one day you will.
L: did Carsyn know her before she was an old lady?
M: (trying not to laugh) no. she's been old since you three kids were born.
L: i really miss her. i wish we could see her more......
