No one gives you grief about dust, or dirty dishes, or an unmade bed.
You can go when and where you please, no permission needed.
You can go to bed at 2 in the morning and sleep til 10 without being made to feel guilty.
You can go to bed at 8pm and get up at 6 if you want and you do not have to be quiet.
You do not have to have dinner on the table at a certain time or else.
You can parade around the house naked if you like.
You don't have as many expenses such as kids to feed etc.
