practice makes

take a behavior you find irritating in someone
and meditate on it:
remind yourself that we are all made of the same stuff:
at bottom, we seek comfort and shirk discomfort
(the nature & content of which is infinitely variable)
and then ask yourself
what kind of need do they address with that particular behavior?
for no matter how sloppily
we all do the best we know to address our basic needs
at the moment

hold your judgmental horses
