I have a lot of amazing friends on Italki. They have made me try all kinds of laughter. Even when I'm sad, they do all their best to make me smile once again.
As for your two sentences, I will choose the second one, "Tears coming out of your eyes!". All my dearest friends on Italki organized for me an international birthday party, or a magical party. They made me laugh till my tears came out of my eyes. I'm really still laughing till today!
They are real diamonds such as your name! :)
