How do you stop certain people from seeing things on facebook?

[Jaz]

well it kinda depends on what ur hiding
some of the time it wont lets u hide stuff
but like when ur posting notes u can go to the way bottom and it say only let then it has a box
with options click it and it givevs u those if its just cerin u click custimiz list and click pll u want

with posts(sharing stuff)
u write whats on ur mind then when ur about to click share dont cuz u dont want everyone to c that so in the box there is a little padlock u see and click that and that will give u opyions

there may be other ways to hide things from certin ppl but it really just depends on what ur talking about
