1. Unlike English, Japanese employs different 'speech styles', depending on who you're talking to or who you're talking about, and all verbs in Japanese have two different 'forms':
Informal style can be used when you talk with your family member(s) or
close friend(s).

5. In colloquial Japanese, you hear often /yo/ at the end of a sentence.
This so-called "sentence particle" corresponds (roughly) to the English, "I'm telling
you."
Use this sentence particle /yo/ when you provide your friend with
new information.
For instance, suppose that your friend does not know whether
Chris plays tennis or not. And, she or he asks you:
"Chris tenisu suru?" (Does Chris play tennis?)
In this context, Response 1 (as compared to Response 2) sounds much better!
