Notes being pushed in your hand

How cool is it when you get a note stuffed into your hand? It reminds me of school when you would pass notes accross the classroom, a little secret just between two. This particular note, as I guess many do, left me a little perplexed. What does he mean? Is he just being friendly or wanting more? Of course I will never call, can you imagine? 'Oh hey the other night you rubbed my shoulders for a bit, wanna do it again? Just as friends of course - yeah right, that would only lead to trouble, which I guess is what the writer was after, a little 'trouble' in his life.
