Flirting frogs

It's that time of year when frogs appear from nowhere to take up residence in our pond for a bit of flirting and mating. There were about a dozen this morning but I fully expect the numbers to increase to well over 50, based on previous years. There are already heaps of frog spawn around the edges of the pond.
I woke up feeling slightly under the weather this morning as if I had a cold coming on but I had fully recovered by this afternoon. I suspect it was the side effects of the Covid vaccine.
