As different from I'm going home in the near future

[joypulv]

It depends on the context. Generally it would not be used that way, because 'go' here doesn't clarify the timing very well. It's often only used as an imperative: (You) Go home. I'm going home would be very soon unless stated otherwise, I wiil go home would have connotations of later, I went home of course is the past.

But some people in casual conversation use a simple present tense for everything, even though it's the past: 'So I tell her I don't like it and I go home, where I let out the dog and bake a cake.'

When my friend goes home, he is welcomed by everyone, But when "I go home" I'm treated like an alien.
I think the above is correct grammar in an isoalted situation.
A completed sentence "I go home." would be acceptable in response to a question like--Where do you normally go during the holidays?
But except for some very specific scenarios, "I go home" has very limited correct usage possibilities.
