1:1 in this case means "one on one". Your manager is asking to setup a regular meeting between the two of you, as the other poster said. The sentence is not quite clear, however, and would be better written as "Let's setup -a- regular 1:1" or "Let's setup regular 1:1s" The first sentence meaning "Let's setup a standing/recurring one on one meeting" and the second sentence meaning "Let's setup regular one on one meetings". Essentially the same meaning, but one way you are able to write singular and the other must be plural. You manager did neither.

まゆみちゃん、こんにちは。 If you are engraving (or printing on, etc) the frame, then I think "Forever and Always" will be nice. Please be sure to capitalize "Always" but not "and". If you are writing it by hand, then I feel like it is a more personal message. In this case, I think "All the best for your future" is more appropriate. In the case of a hand-written message, it should convey your wishes to the other person(s). If "Forever and Always" is written by hand, it could connote a different meaning than you intend.

ねこちゃん、こんにちは。

 

「ズバリ」は「断固」ですか？それはdecisive, frank, direct,と思います。

 

 

アメリカでは、大人だ時に二つクラスのタイプがある、と思うよ。大人のクラス（アダルトのクラス）か大学。自分で、アダルトの方がもっと良い。トピックはもっと洒落（しゃらく）ですから。

 

Please forgive my poor Japanese.

When I play this game with my friends and in my Japanese class, we use the last phonetic to start the new word, not the last vowel.  So, in the 海 example, we would use a word that starts with み (mi) not い　(i).  By using only the ending vowel sounds, we can only use Japanese words that start with a vowel, which limits the vocabulary.
