My friends started having children after college, while I was pursuing this crazy acting career and living hand to mouth. Plus, all my boyfriends were artists struggling to make a living. Having kids didn't make any sense - why would I take on more of a financial burden when I couldn't even afford a dog?
A lot of times I think the cast members, the lead characters in a show really set the tone for the show. On some shows, the stars of the show will just be whining and complaining and spending the whole time texting their boyfriends on their Blackberries, and there's just no attention given to the work.
