Life lessons is about an artist Lionel Dobie who is having issues completing his work.
On the set of life lessons I think the placement of her room and where Dobie puts his canvas is really important. Prior to Paulette staying with Dobie, he struggles with inspiration and can’t paint. It is only when Paulette gets there he is able to bounce emotions and get inspiration in order to paint. In the scene where Lionel is looking for something to do and plays basketball, the “backboard” is her window. The whole concept of a backboard is something to bounce off of. So when he throws his basketball in the window/backboard it goes to her and she gets irritated. Right after which he goes up and tries to kiss her foot, and gets rejected. With all this built up emotion is only when he is able to paint and make his masterpieces by using this girl.
I also thought that the set described Lionel Dobie. It was a large spacious house apartment but it was covered in paint and dirtied up with odds and ends thrown around. I felt it described Dobie rather well in the sense that Dobie is a bigshot in the Art world but really does not really care about it. The only thing that is clean in the apartment is Paulette's room. Also to show that is all Dobie cares about we only see her room, there are no shots of where Dobie sleeps or does anything for his own well being. Where as we see Paulette relaxing (or trying to relax) in her room, on her bed.
