It works like this – if you are going to use punctuation to separate an interjection, you have to completely surround the interjection. So - always 2 commas (or dashes, for a stronger separation)

But if you don’t want to treat the name like an interjection, but rather as a part of the normal flow of the sentence, then you must not use any punctuation at all.

It’s just a matter of style – but if you choose one style, you have to stick to it.

A: unexpectedly my old friend showed up

A: you are giving a compliment to both and comparing them to other bosses and friends. They are the best friend and boss that you have ever known. Since they are the best you "couldn't think of a better boss/friend". Hope that makes sense and answers your question.

A: It means “you’re a great friend.” There’s some implication that this person thinks they’re lucky to have you as a friend.

A: Do you feel comfortable?
No, I don’t feel comfortable.

A: Without context, it doesn't mean anything. If "made into gold" is an expression used among people who play League of Legends, then that's fine. If it's being used perhaps to express that an account became very good or rated as "gold", then it should be "my friend made my account (become) gold".

A: She friendzoned him
She got friendzoned
She sent him into the friendzone

A: ❌“Do you got hair cut?”

“I did! How does it look?”

Here are some, but there are many more common phrases ^ ^

However, asking someone if they slept well is not usually something that would be done routinely (like as a regular/daily greeting) or randomly (without reason).

1. You know that they slept somewhere new / different / unusual; or

2. You want to make sure they had a good / long sleep because today will be very busy, important, or exhausting; or

3. You are concerned about their health / wellbeing (e.g. because they are sick, jet lagged, stressed / nervous / anxious, or they have chronic sleeping issues)

example → role model 🟢
the friendship → my friendship 🟢
