The wheelchair

While I sat in the reception area of my doctor's office, a woman rolled an elderly man in a wheelchair into the room.
As she went to the receptionist's desk, the man sat there, alone and silent.
Just as I was thinking I should make small talk with him, a little boy slipped off his mother's lap and walked over to the wheelchair.
Placing his hand on the man's, he said,
'I know how you feel. My mom makes me ride in the stroller too..'
