People definitely look at me differently, but that's probably because I had some major dental work done that I neglected when I was drinking. Truth be told, my grill was a hot mess and I was so wasted all the time I just didn't care and didn't smile and when folks saw my teeth I didn't receive the most pleasant reaction. But now I smile at everyone (because I'm not hungover, and because I actually can) and everyone smiles back at me. I feel like I'm much friendlier and people are in return much friendlier to me.
People do act differently toward me than they used to. But that's because I act differently than I used to. I have more meaningful conversations with people, I actually talk and behave like an adult rather than a child, my boss knows he can count on me and I won't let him down...There's lots of "differents" now.
