can someone please tell me the meaning of the lyrics of this song entitled 'shakespeare's carol'?

Question

here's the lyrics: (i need to know what it means)

blow, blow thou winter wind,
thou art not so unkind
as man's ingratitued
Thy tooth id not so keen
bcoz thou art not seen
althoug thy breath be rude

Heigh ho! sing heigh ho
unto the green holly most friendship is feigning , most loving mere folly
Then, heigh ho the holly, the holly.
this life is most jolly..

Freeze, freeze, thou bitter sky
that dost not bite so nigh
as benefits forgot
though thou the waters warp,
thy sting is not so sharp
as friend remembered not..

Answer 1

Very basically..........

He is comparing the attitude of people to familiar winter and Christmas things. However bad the weather may be, some people are far worse.

Ingratitude is worse than a winter wind.
False friends are worse than the prick of holly.
To be forgotten by your friends is worse that being freezing cold.
