Well, life? Just managing your own home requires a lot of organisation, and even if you do care, you will have a hard time to cope for long without some tools to help you (calendars, notes, schedules, only to name those). Unless someone does it for you. Or unless you live a very simple life that can fit in your head all the time, of course. Likewise, seeing your friends fading away, not responding to you might be because they've just forgotten you, or don't want to see you anymore, or they are just drowning in their own life. And maybe with time they will cope/react differently, maybe not. Considering that friendship/care only can be spontaneous and not prepared/provisional, this is disingenuous and borderline toxic (to both you and others).
