I need some relationship advice. My friend and I have known eachother for a while now and weve become best friends. Today, we were walkinfg to our bus together and my brother came up behind us and put a hand on my should and myy friends shoulder. He said something like loh now" (i didnt hear what he said exactly) and then started holding my hand for a while. He did it again later on the bus. What does that mean?
