Friends what are they

Friends what are they?a snake that could bite you any day,they smile at you like all is ok or there okay with you,but there not.You would be shocked to hear what they say behind your back,but not what they say infront of you,they laugh and smile with you but in reality they cant wait for you to fall.they are like blood sucking mosquito's that will suck information from you to give to your enemy's,friends they dont stay for long,they change like the weather or a song.Friends what are they? I keep wondering where are they when im not okay,friends can be our worst enimies ,friends are always our foes,lets choose our friends wisely because we dont want snakes,we dont wanna get hurt or betrayed.l,friends what are they.
