Neo4j query relationship property

Neo4j newbie here. I have a graph database with node as Person, edges between nodes are relationship POSTED, POSTED has property "message", now I would like to return relationship with certain message. I wrote query like:

MATCH (ppl) -[p:POSTED]->(s)
WHERE p.message = "How are you?"
RETURN p

It returns nothing.

What is the right way to make relationship queries? Can I make some queries like:

MATCH (a) -[:KNOWS]->(ppl),
(ppl) -[p:POSTED]->(s)
WHERE p.message = "How are you?"
RETURN p

Creating a lot of same Relations between two nodes is not a good idea if you want to create something like a chat.

In fact, it'll be a lot more easier and faster to create a model like this:

(:User{Foo:"Bar})-[:POSTED]->(:Message{content:"Hello World"})-[:SENT_TO]->(:User{Foo:"blabla"})

This way, you'll be able to store way more thing in your messages and It's easier to do operations with nodes.
