Nothing uncivil here.

This use of "thanks" reminds me of how some people have distorted and diluted the word "thanks". It's often not meant as a real costly self-exchange, it's instead aimed and intended to bite, to be sarcastic and flippant.

We should reflect on what was a beautiful word of self-gift, and do what we can to curb our flippancy and perverted use of it.

The devil's work is to take what is good and distort it. We shouldn't cooperate with his ugly work.

We see other examples in the beautiful words surrounding marriage. Marriage, love, sex have all been corrupted.

In a small effort to restore the meaning and value of the word, let's ponder the beautiful words of the preface from the Holy Mass:
"It is truly right and just, our duty and our salvation, always and everywhere to give you thanks, Lord, holy Father, almighty and eternal God, through Christ our Lord."
