Mylanji

My sister has put this beautiful black and golden mehendi on her hands. In Arabic there is a text - alhamdulilah. I’m taken by it and want to use stencils to draw the same for me. As she goes to have bath, I play with my nephew and keep pulling g down his pants to irritate him. I do this a couple of times and he is angry at me. My niece is also upset at me for this. My sister comes after bath and I’m worries he doesn’t complain about it to me. I’m feeling worried on how to resolve things with him.
