I Never See My Mom

Many days when walking through the streets, I'll think I see my father. Even though the reality is, there's no way he'd come here without telling us ahead of time, I can't help but look at the Dad-Impostor, until I've figured out what makes this man not my dad.

Oh, well my dad wouldn't read the newspaper while standing around outside a building.
or
Huh? My dad doesn't smoke.
or
Of course my dad wouldn't ever wear that.
or
Hey, why is my dad kissing that guy?!
