Who Am I?

Obedient, Knowledgeable and Proactive
Versatile yet strong, soft yet assertive
Lightning fast with a killer instinct
Is it me? Or my persona is distinct?
Looked upon as a man of substance
I just wonder who I am?

Everyone has the right to think
I'm there for them, at eye's blink
Friend, son, husband, and father
Numerous relations, to fulfill and gather
Unfeigned within or just a sham
I just wonder who I am?
