I will teach English 'Until the cows come home' What does this English phrase mean? #duncanenglish

One of the wonderful things about living here in the countryside is

you never know what you are going to see next.

There are all sorts of things lurking in the bushes, behind the trees or over the hill.

There are many words and phrases connected to wildlife.

For example, there is a great expression that talks about waiting for something to happen,

or doing something for a very long period of time.

We might say that we are going to do something ‘until the cows come home’.

That means you will do something or you will carry out a certain thing until the very last moment.

Your last opportunity or chance to do something, or the period of time in which you are going to do it.

I am going to carry on teaching English...

until the cows come home.
