At one time I would have been appalled by the overuse of "like" and the fact that younger people tend to go up at the end of sentences.
Then I realised that speech and language are always changing! You have only to observe how much speech has changed in the last 100 years. I expect if we heard speech from 500 years ago we would struggle to understand it.
And to think how languages have evolved in the last 1000-2000 years! No, we have to accept that speech and language will be forever changing.
