ね and よ, the ends of sentences
[Sentence] ね / よ
ね invites agreement, close to 'isn't it'. よ adds information the listener does not have, close to a light 'you know'.
The mistake to avoid
よ used too firmly can sound pushy. When in doubt, leave both off; a bare sentence is never rude.
Examples
いい天気ですね。
いい てんきですね。
Nice weather, isn't it.
これは私のですよ。
これは わたしのですよ。
This one is mine, you know.
