a hobo is a migratory worker who likes to travel,
a tramp travels without working,
and a bum does not travel or work
I'm glad his namesake carries a work ethic and some culture! ANYWAY ... tonight was a chance to spend a little time with him at the softball game before he goes to the East Coast at the end of the week. He made friends with a toddler, never jumped once, and every time she cried he ran to check on her. What a sweetheart!
