When you travel/move, enter into a new environment, you get to be the current version of yourself, and have everyone interact with that version of you. When you are at home or in an older environment, you have people who are simultaneously interacting with many different versions of you at once (ie people who knew the high school you, college you, early career you etc). This is challenging because it pressures you to also carry on multiple historical iterations of yourself, rather than being truly the present version of yourself you want to be in that moment.
