Humans get very angry with each other over silly things.

We generally use "angry with" when talking about being mad at a person (or each other).

They love to talk about the weather every single day.

We use "talk about" to introduce the topic or subject of a conversation.

They are also very good at sleeping through loud noises.

We use "good at" (not "good in" or "good on") to talk about someone's skills or abilities.
