ten thousand different things

im reading the kitchen god's wife by amy tan and this line, touched me. that in the end, i cried.

"..the saddest part when you lose someone you love - that person keeps changing. and later you wonder, 'is this the same person i lost? may be you lost more, may be less. ten thousand different things that come from your memory and imagination - and you do not know which is which, which was true, which is false.." - amy tan
