My two girls are over five years apart in age. Right now at eight and fourteen the age spread seems larger than it ever has.
Sometimes at night, when my youngest daughter is supposed to be in bed, she will write notes to her big sister and slide them under her door. If her big sister isn't too busy she will often reply and shove the note back out under the door.
I could hear this happening last night and I let it go on for a while. Finally, after about ten minutes, the sound of feet running up and down the hall suddenly stopped and I heard my youngest climb into bed.
When I went up later to tell my older daughter it was time for her to go to bed she showed me the last note.
My eldest daughter had written,
R- Please stop annoying me.
My youngest had replied,
J – Never. XOXO.
We're keeping this one.
