Can mortals talk to Greek gods and goddesses?

I mean in a myth.
I have to write one, and I forgot if they could or not.
For example, a mortal decides to steal something of Zeus's, and Hermes hears.
Hermes goes and tells Zeus, who then tells Hermes to trick the mortal into tell him the whole plan.

So I guess what I'm asking is, could Hermes go and talk to the mortal?

I have writers block, its my dream to write a bestseller, i need help my book is based on greek mythology, Artemis, Zeus, Ares, Aphrodite...any ideas? im planning on giving the money to my family, help?

The guy I did my research on was a guy named Sisyphus, he betrayed Zeus and a bunch of other things. What my teacher wants us to do is write a research paper 1200-1500 words (I'm in honors lit) and I have NO idea how to start the intro paragraph. Any help?

Yes this is homework - or part of it anyway, I think I'll make it about how Zeus gave Artemis the silver bow and arrows, hounds, stags for her chariot, and nymphs, but how should Artemis approach the matter and how would Zeus answer? This is all I have:
Artemis: Hello Father.
And that's where I'm stuck. Please help!

I am so stressed out! I need to write a song to the tune of a modern day
Christmas song, but using greek vocabulary such as Zeus, Mt. Olympus, polis, acropolis, Phynx Hill, Parthenon, Athena, etc. Please help me! The song also needs to demonstrate the meaning of each word used.
