You are too/ very kind to me [closed]

What is the difference between you are too kind and you are very kind?

too kind MacMillan Dictionary

used for thanking someone in a way that is very polite but not completely sincere

And from You're Too Kind - A Brief History of Flattery By RICHARD STENGEL, we can again find some negative connotation. Depending on the context, of course. The article is a fascinating read and somewhat a narrative etymology of self love and flattery.

That ironic tone is so often the cloak for all flattery, indeed all praise, these days. What we think of as flattery is usually delivered with an air of arch knowingness, a kind of self-consciousness that says, We all know this is flattery, so don't consider me a weaselly little brownnose for saying it. In fact, these days we struggle to invent new ways to praise people because the traditional methods are seen as a worn-out currency.

This leaves the other compliments such as kind and very kind to their literal meanings, stripped bare of most other connotations. Of course, context is critical in perceiving the meaning of 'too kind' and 'very kind'.

No, 'You are too kind' does not have a negative implication. It's a rather exaggerated way of thanking someone, suggesting that they are showing you more kindness than you deserve.

'You are too kind' is merely an idiom. In normal conversation, it doesn't convey any sort of negative connotation - but it can be (and is!) used sarcastically or as a form of flattery, which is where that negative connotation would arise.

'You are very kind' is similar in its meaning but seems more effusive and heartfelt (though that is my personal opinion on the matter).

I'm sure there are regional differences in how often they crop up, but their underlying meaning is the same. Therefore, they can both be suited to a wide range of situations - it depends on your personal preference for one or the other.
