The New Me?

I am venturing back to the life of the working woman. Working out of the house that is. I decided to get a part time job for some extra money (duh) because I would like to buy myself something once in awhile not just kid's stuff and to get out of the house to meet some new people.
My neighborhood is great, if you are over 50, but as for young hip mothers and children? This neighborhood hasn't got it.

I have an interview next Tuesday with a PR company that is local and I totally feel out of my element. I haven't worked in an office in over four years. Is there anything new I won't know? Will I be that odd "mother" type in every office that all the younger kids hate because they are doing all of their work efficiently and making them look bad?
And what the hell is "professional dress" anyway? I think I have always had a professional dress code in offices that I have worked in, but what if I really didn't? Should I go out and buy a ball gown now?

I hate that this is making me doubt myself, just because I took time out to be a mother to people that one day emerged from my body, doesn't mean I have lost my skillz. Or does it?

Oh and I joined a gym yesterday that has a kid's room and trainers and lots of yummy stuff. Even yoga my favorite, but I haven't done yoga since I was pregnant, are there any new positions I don't know about?

Are your guys proud of me?
Seriously, who is this person? Can't be me.
