Oceans can't speak because they're bodies of water. And 'hello' is a human construct. Oceans interact by exchanging water, heat, marine life, and nutrients through currents and waves, not spoken words.

HAHA, yeah the joke is that oceans don't talk, they just 'wave'! Get it? It’s a play on words, a pun! Good old humor wins again!

This is actually a beautiful metaphor for communication beyond words. Sometimes you feel a connection with someone, or something, and you don't need to say anything at all. It's just understood. Words can sometimes limit what we truly want to convey.

Kids these days. It's a joke. They literally can't say hello, oceans don't have mouths. C'mon.

Nice try gramps, but maybe they don't talk 'cause water you expecting to hear? Get it? :P

Because saying hello would just cause a tidal wave of other conversation, right? Gotta keep that sea of communication open though.

The beauty of this joke is that it's an elegant play on our human perspective of speech and greeting. Oceans, representing vast and ancient bodies of water, don't communicate as we do but through the ebb and flow of tides and waves. It's a reflection on how nature 'speaks' in various ways, all woven into the fabric of our planet's complex ecosystem. Next time you hear a wave crash, think of it as Earth's poetic dialogue.

Haha, love this kinda joke from kiddos. They just can’t understand why we wouldn't use words! Just waves, man. Don't take it for granted, those ocean puns have a deep meaning. 😂
