How would you feel if I told you I look through my brothers phone when he left it at home.
Why would you look through your brother's phone? Were you expecting to find something?
Because I was curious what was on it.
I can't believe you did that, you really shouldn't have looked through your brother's phone. You should respect people's privacy.
What? I was curious. I already knew he was a cheating piece of crap.
Even if he is cheating it is wrong to go through someone's messages and photos without their permission. If he finds out you can really damage your relationship. Do you have plan to let him know you know about his antics?
