I'm not a father, but I did get a gift of sorts today.
My grandfather has advanced Alzheimer's disease and is barely verbal. Ask him a question and you'll likely get a "yes". Did you like that ice cream? Yeah. Would you like to stick a cockroach in your nose? Yeah. There was a time when it seemed like he recognized me, but those times seem to be gone now.
Dad and I went to visit him today, and I got a whole sentence out of him. He grabbed my hand, looked at me, smiled, and asked "How ya doin', old buddy?"
Awesome Father's Day.
