I like the feel of the space A but what about the structure shut up and go get me some coffee can make it fit into our budget? E C Apprentice I’m so HAPPY Atlantic Team Dynamics Winter Quarter Owner
Well, I’ve graduated, so I’m out of here! A Get your own coffee Stratton Who is going to get me some coffee? Now, how do we make our ideas buildable? E C Apprentice I’m still HAPPY Atlantic Team Dynamics Spring Quarter Owner
