obsession with dates

i have to get rid of this one very soon. one, it is very fast clogging the mental space since i have this stupidity of remebering distant people's anniversaries, birthdays, their children's birthdays... so on and so forth.
two, this creates an unsaid expectation in the mind that they reciprocate mine... that is a problem on since people whose dates i remember may not necessarily consider me that important to be able to remember mine... but the mind bugger feels sad... so either i get rid of the expectation or remember to forget dates... let's see which one is easier.
