when i first got sober ('87) i had a hard time with the whole reality thing......as in i didn't really trust MY OWN concept.
i remember being in the kitchen with my roommate and banging on the fridge, asking:
is this a refrigerator????
yes he replied.
and it's not BLUE right?
no, it's not blue.
it's WHITE, right?
yes.
ok this is good, i could now identify a kitchen appliance AND it's color. when things got a bit sticky, as they do in early recovery, i often gave the ole fridge a good solid pat.....yup, still a fridge. it helped to ground me......give me a starting point, one thing i could rely upon.
