Never in my life that I will laugh at you. We do misstakes like this, it is human to err.
But I will laugh with you, let's laugh together. This is not the last blunder you will do in the future, it's only the latest, you will do plenty of them. So will I!
Every time I do a blunder like this I swear for a while, then I laugh a bit. The world is not going under, it will continue. And we have fun, don't we?
