Part 1 is the first act, somewhat expanded. The additions are pretty seamless and add a bit to the story. Its been a long time since I saw the play, but there is only one part I was sure wasn’t in the original
spoiler
(A Cameo with Kristin Chenoweth and Idina Menzel)
If you are into the play you would probably like it. I went with my wife and daughters and they loved it. I found it enjoyable enough. As someone who isn’t super into the play, it was paced well, with some good comical elements.
Sounds like you are too blunt. Never tell them no. Listen to their problem and just reply with a ‘Id have to look into that’, or an ‘I can come over when I get a chance’. If they persist, have a couple projects they can help you out with and tell them 'sorry Id love to help, but Im (going to the dump / painting the kitchen / gotta do seasonal yard work / etc). If they offer to help you, then you are kinda on the hook to help them. If they dont follow through… you can subtly bring it up (still gotta move that couch). You dont have to be a dick about it. It can be fun messing with folks.
Honestly I’m tech support for some people, but I need help with some of the more advanced stuff, so I have a tech guy too.
