See the work through !!!

Renee	I'm proud of working with you and delighted to assist all of you in work.
Michelle	Well, we are going to make a product presentation to Topcraft Co. I think it's about time for you to be in charge of a case like this.
Renee	But I don't think I'm qualified yet. I'm not much of a talker.
Michelle	I know this might be a rather giant step for you, but you have to grow into this. You don't want to do the chores or run errands for somebody all your life, do you ? Think about that.
Renee	Maybe you're right. OK. I'll take this job and do my best to see the work through.
Michelle	I'm happy for you. Welcome to the real world. It's not perfect, but you're gonna love it.
