with the bigger room, you'll have more space to sort of redecorate it however you like; you're going to be able to put a lot more stuff in it like furniture etc.

most people look to expand their horizons, to be bigger and better then they were yesterday.

I say take the bigger room

My dad said that I can redo my room, then I asked him if I can have his master bedroom he agreed to give me his room, which has a bathroom and huge space outside of the bathroom which is the bed room.. Question is should I take his big room while he is left with my medium sized room?
