So, you have lived alone for the best part of your 20s and early 30s in a metropolitan city. This means that either you are a lousy roommate or your threshold for lousiness from a potential roommate is very low. You have grown used to the freedom, the surroundings, and the fact that you don’t have to do very little adjusting.
This includes watching the television programming that you love, binging on things that you think that you can’t live without, and walking around naked in whichever state of odor that your body is in at that moment. Yeah, you don’t even care to draw your living room curtain while strumming your guitar naked watching some crazy stuff on television.
Yes, you are being selfish and self-absorbed. But don’t frown. You should probably consider yourself lucky. You had the opportunity to do that. Savor every moment being alone in your apartment.
But please, please, please don’t think that you can somehow fit in your parents’ stay as if nothing ever changed. You will be put through the mental agony of adjusting to their idiosyncrasies and you will not be prepared for it. Not in a long shot.
