Just because your brain is able to keep track of your friends and actively remember to interact with them, doesn't mean everyone is like you. People who are not neurotypical can have very close friends and family and not realize that 3 months have passed since they last called home or checked in with a friend. It's so easy to forget that other people's brains don't work exactly like ours; remembering that is an extremely important habit to exercise.
