Every 9th of a month, the Official Day of Ignoring is celebrated.
On this day you can easily and without any guilt or shame ignore everyone and everything you don't want to waste your precious time with.
It has its roots in the urgent desire to ignore annoying people and tasks, something all humans share.
So: GO and Ignore!
A:"Hey. How are you? Wanna hang out?"
B:*ignores A, because it is Official Day of Ignoring*
