Becoming Dad (and Mom) 2.0

Lately I've noticed something weird, something I'm not sure I like.
It seems every time I walk past a mirror I get a glimpse of my father.
Now, don't get me wrong here. I love my dad. I have great respect and admiration for him. He provided a great life for his family and gave us lots of support. So, in that way, I'd love to be like my dad because he set a great example.
If I'm being honest, the part I really struggle with, though, is the notion of looking, sounding and acting like my dad in almost every way. I've not only developed many of his mannerisms, I use many of his same expressions and I swear my voice sounds exactly like his.
