Evil Twin

I work with this cook, we will call him Dominick. He is 36, been a cook since he was 17, really good looking, and very charismatic. Sound familiar? He and Todd are two months apart. Here is the difference. Dominick has his drivers licsence, owns his own home, has a beautiful car, likes to drink at home, likes video games and football, so do I but Todd doesn't. It's creeping me out how similar they are but how different. It's like they are twins but one is good and the other is evil. Todd and I are basically done but not official yet. He refuses to stop drinking in public when I told him that my dad is high up in charge of the sheriff's department, people will see him and he is actually going to be eligible to get him licence back in May and he told me flat out that he is worried about it because he's not sure that he is going to be able to hack it. He has a attitude that he's above the law and is sometimes vocal about it and I really need to do what's best for Logan, He can't have a role model like that. I know what I need to do but it is so hard to do the right thing.
