Well picture this, i was arriving to a pool party and i start to say hello to everyone, so there is this guy, who was my niece´s boyfriend so i start telling him who was that girl in that ugly swiming suit, at the beginning no one said nothing and i start joking about her, but no one againg next to me said nothing again, then suddenly my niece´s boyfriend left the circle so everyone start to laugh and my niece told me...are you crazy you where talking about her and it was my boyfriend´s sister...ups...

So sometimes it is just better to keep quit...
