If you were to describe what it means to be a man in one word, what would it be and why?

Tim ~ “I asked him why he chose this word. What I discovered is that this is not only a word that defines what he thinks it means to be a man but its also a tribute to his recently deceased granddad. As John started describing how his grandpa was a solid man I could almost feel like he was in the room.”

Word: Solid
