I’ve had that feeling a little too, it’s kind of like if you were left in an open field, staring into the summer sky, and all you hear are birds whistling and the careful breeze coming and going over your cheek. Heh, for me, I get that feeling in our schoolyard, when everyone is gone. But remember, eventually, you’ll hear someone call out “Come on! It’s time to go now”, and you let out a “Coming!”. Though you don’t mean it, really. Instead you mean to turn to the surroundings and say “Let’s meet again sometime,” before getting up, brushing the grass bits off your creased pants, and leaving.
