This is the brother having a nother OCD issue with his room. he is not liking the colour of his room and his sister walks in realising something is wrong so she asks whats wrong
Once the sister has figured out that he doesn't like the colour of his room she understands. she doesn't argue about it but instead offers to help him and to take him shopping. This is the sister understanding whats wrong and wanting to help.
Once they got to the mall they went to a shop to find new things for the brothers room. He told her that he likes blue so she tried to find mostly blue and something that will make the blue fit well with. this is the sister trying to find what he likes so she can look for that type of thing
They went to sit and eat and the brother was annoyed because the colour of the food court was in a colour that he didn't like. The sister understood that he was unconformable with the colour of the place
They left early because the sister understood he was not conformable with the colours. Once they arrived they discussed when they should start getting the room fixed. This is the sister trying to understand how weren't it was to fix the problem for him
When they finished the bedroom makeover the brother was very happy with it and the sister was happy that he was happy that he liked it. The brother is very thankful fro his sister because she went out of her way to help him overcome his OCD issue
