One day, I was just floating along wondering about how long the last two periods of my school schedule were going to feel, when I received a text message from a good friend of mine. She said that she had drawn a picture for me, and being the artist that she is, I was excited to see it. It turned out to be a picture of a inside joke that we had made up a few weeks beforehand. She didn't tell me she was drawing the picture and we hadn't necessarily spoke of the joke recently, so it was a complete surprise. It made my day, and I still laugh when I look at the picture.
I don't know if other people find little surprises like this as pleasing as I do, but if it makes their day as great as it does mine, they should.
