How do I explain to my sister why I tried logging onto her Facebook?

[dude]

I wanted to stalk the profile of one of her really cute friends, but when I tried to log on, it needed me to identify photos of her friends which I didn't know how to do. How do I explain myself? Maybe I accidentally typed in her username and password? Thanks.

Say you have been practising some hacking and thought it would be fun to try it onto her account. Tell her it was all just to see my ability and that you would've not done anything.

Just tell her you wanted to stalk one of her friends in a sarcastic/or serious tone. Or you can lie and say that you wanted to prank her

tell it wasnt you. or blame your mother. or tell her that u are worried about her. or in the worst case scenario tell her the true..

[rosebuds]

tell her that u r making sure her account is safe, and that is not easy to hack in to it. XD

Tell her you were planning on fraping her Facebook.

Tell her straight up that you're interested in her friend, it might work as an icebreaker to get your sister to introduce you two.

Be hard to explain that. About like explaining to the police
why you robbed a bank. LOL
I am sure you have Face Book. why not just invite the friend to be
a friend on Face Book?
