Because I grew up the youngest of Three I think it allowed me the advantage of adapting to living with other people..better. Forcing someone to deal with habits outside my own was never a struggle. I had to share closets, spaces, and learning how to organize myself was something easy for me. You learn quickly what to touch and keep to yourself rather than argue over how you want socks folded or something trivial like that. I just go along with many of my mates habits and now having the chaos of a 2 years old I have come to understand these habits really are just built into personality with birth and really not something you can learn.
True you can act like a particular way for a short while but really training your brain to do something it naturally doesn’t want to do is tricky. For example what a person does once they arrive home is all habit. It’s autopilot for most people coming home is a routine leading to that amazing couple of hours of relaxation. I personally walk thru my front door, take my boots off, followed by my work pants. Slip into something more comfortable and relax all after of course greeting my daughter and wife. It’s become an added bonus that the second the door opens I hear now the scream of “DADDY!!” AND then she goes right back to whatever it was she was doing with a “Hi hun” from the best part of me.
One of the funnest thing I have ever seen was an ex girlfriend of mine would walk thru the door to her home and instantly fling her shoes across the room like it was a soccer ball. Keep in mind the room was huge and it was just comical to watch. I suppose we all have our habits and in that we make ourselves comfortable.
