Do you ever have a song, an idea, a storyline, or an image stuck in your head? And it just refuses to go away? For some time at least. I have this with music—it could be a song, an instrumental piece, a jingle, etc. This becomes my ‘now’ song, and the “nowness” (pardon my English here) could be for any length of time.
I’m sure you’ll agree that no further explanations are needed here.
Happy Independence Day :-)
