When my youngest daughter was about 18 months, she greeted her Daddy when he returned home from work,
"Hi"
Pause.
"More hi."
She's 28 now and we still laugh about it.
I often have trouble sleeping at night. On one of "those" nights, I rolled over toward my sleeping DH. He opened his eyes very wide and yelled "rawr" into my face. Then he started to "rawr" a second time, but woke himself up. I asked him why he was roaring at me - his answer was - "There's an alien under the crib."
We both cracked up.
