Nonsense?

If you really s-t-r-e-t-c-h it, it could be interpreted as a clever statement about life. However, I think what is probably intended is "people have different attitudes...".

Thanks very much Philiip! That was from a book I read. It might mean the "stretched" thing.

I wouldn't say this in everyday conversation. I am not an attitude, never have been.
I do have lots of attitudes, and I exhibit my attitudes.
Perhaps the author was using a literary device to make some point - that some people have such strong attitudes that they become a caricature of those attitudes. But it's not an elegant device, either, in my opinion.
