Why somebody say? ppl= it should be (people) don't short form

We have our style of speaking and it is often incorrect. Sometimes correct English sounds wierd.

it is considered "slang" and these days native english speakers predominantly prefer to use such slang, especially americans. they seem to really love their slang. canadians do you use slang alot, but we are more reformed.

We Americans like to talk in our own style. You'll hear words like "yous" "ain't" and "y'all" Such as "y'all come back now ya hear"

They are native speakers, i mean i heard it from an American TV shows sometimes and some ppl in the real life. I thought it is kinda a rule or somethin :)
