My daughter used to say hangerbur instead of hamburger. And ameenamint instead of elephant. We didn’t correct her. It was too cute.
Many years later when my daughter was pregnant she asked me what I wanted to be called. I said “Grandpa. I earned it.” When my grandson began talking he started calling me Boo-kha. I have no idea where that came from, but I loved it. When he got a little older he switched to Grandpa.
