i'm ready to tell you that you don't know what this is

Today my dad gave me the old cellphone that I used for two weeks before it broke down, because it was working again. Although it doesn't have a plan on it anymore. I went through my old text messages, and found that there was one that I had not seen before, on October 27th. It was simply this:

"<3!"

And yet it made me smile.

Tomorrow we'll be doing playing tests in band, and I've already hatched an elaborate plan that involves note passing and subtle signals.
