Why Carly Carrothers' Will Not Fall for Mackenzie James:

1. He was a kid. (An adorable little girl, but a kid, nonetheless.)

2. He's your irresistible yet demanding boss.

3. He has a kid. (Remember what happened last time you got involved with a single dad.)

4. He's so sexy you can't think straight when he's around.

5. He has a kid. (What if you get attached to the sweet girl and her daddy doesn't pop the question?)

6>He's got this thing against marriage. (Okay, so they all do. But remember—you want a husband!)

7. He was a kid. (So stop straightening the little angel's pigtails and kissing her Big Bad Dad senseless!)
