Changing My Friends face from boy to Girl without knowing them

Last year I visited to Kumrat which is called the beauty Queen of Pakistan. There we were the guests of my brother friends.
They were really friendly and looked after us as a family of their own.
I really was too happy to be with them for more than a month, but unfortunately we should have to return to home in order to continue our study and business.
I took picture of them as a girl without knowing them and their reactions were so laugh and beautiful when they saw their pictures

This one is my nephew, he always teases me to take my picture as a cat or as a girl, he is sooo Naughty.

This one too

He was so humble man, we called him the father of murmuring.

She is my friend sister, she loves me too much when ever I visit to my friend she is with all the day there.

He was the best helper in all of their brothers, He doesn't leave us alone even for a short time, and even he slept with us in our night sleep

Abdullah is our team partner in our every trip, i also get a picture of him when he saw his picture, he was full of laughter and was laughing to himself and mine too.
