The problem: People feel forgotten or treated without respect because you forgot those small favors they asked from you.
I am sure you know it: Your girlfriend/wife/colleague asked you for a little favor and you forgot it although you definitely like them and want to fulfill their requests.
The reason: You are somewhere else with your thoughts and not completely present.
In most cases when you are asked for a little favor you are asked while you have something completely different in mind. And actually your first and only brain wave is that thinking of that favor is not important now.
The solution: Pay full attention when your beloved ask you for a favor and set exclamation marks in your thought.
Bear it in your mind what you are asked for and set a date and time (also in your mind - not only in your calendar). Build memory aids that create links to that to-do. Be present with your mind and soul. Then return to your current work. Only if you really got it you have planned that in your mind to do it.
