There has been a sudden change in tempreture in our part of the world of late, however,  there is still no need don underwear under one’s kilt. I mean, why would you?

The north wind doth blow,
And we shall have snow,
And what will the swallow do then, Poor thing?
Oh, do you not know
That he’s off long ago,
To a country where he will find spring, Poor thing!
