I don't think it's ok to invade someones privacy. I think you sould only invade someones privacy if your trying to look out for that person. If you do invade someones privacy and find out something that your not supposed know, i think you sould keep it to yourself. Invading someones privacy only causes drama and a lack of trust between people. If it gets to the point were you have to invade someones privacy, then you proply souldn't even be around that person anymore. Some people care about there privacy more than others, so you sould be careful with what you say or know.
