Thanks for contribution! Only a small Markdown issue here.

This is one of the "sing-song" exercises @neenjaw suggested to skip. I do not know why, but maybe this should be the last exercise of that kind until we know the reasons. There is enough others to choose.

I didn't think about that before completing it. I'm OK with rejecting it, too.

Thanks - one last time for today - for contribution!

I'll not do more exercise today, nor the next days, I think. Need to recharge my batteries.
