Trying to describe chemo brain:
It is like you have holes bored into your brain.
You can touch it, feel it, see it, smell it, taste it, hear it... but you have no f-ing clue as to call it.
Oh, and it is a familiar it.
So, if I look at you funny, and then go up and lick you, THAT IS CHEMO BRAIN.
I need something to lick...
