Agree with your defence for the validity of words of affirmation as a love language especially the bold part. As a people known for their knack for poetry I was surprised why "the word" gets the bad rep of a ne'er-do-well when it is the very thing that makes or breaks a relationship when everything else is a given.
Lol @ you filing away what people say, I'm the same, it's annoying especially when someone relates something differently from how you remember.
While actions certainly do speak louder than words, a true utterance of appreciation and its soaring wings of sincerity (at the risk of this observation being misplaced, the Islamic concept of
Ihsan comes to mind) reaches the heart of the recipient deeper than most acts of service ever could which in turn could be performed without effort, soul or worse yet with ulterior motives. I think we all can differentiate genuine appreciation from false deference for the most part but we are not immune to succumbing to the patina and pomp of unearned praise.
As far as I'm concerned the delicate/fragile nature of words and their meanings due to this dilemma of discernment adds all the more value to this love language. I guess you and quite a number of others on this forum who come across as highly attune to the nuances of tone, choice of words and occasion (paraphrasing an earlier post of yours) can appreciate a literal bon môt because of that, since there is a hypothetical Damocles sword of deception ever looming in the atmosphere above, hung by a single filigree thread of fidelity, ready to strike at the very heart of the word. But in the end "The tongue is mightier than the blade".
Thus true words are king in terms of love language (quality time + physical touch being queen) since they are the most versatile and personal to convey the most intimate thoughts of why in particular you feel this very affection at that very moment for your loved one.
I had to think about that for some time. I think it was mentioned in this thread earlier. I have nothing against thoughtful gifts with meaning which is just another form of quality time your loved one spent on you in your absence, while the gift is the physical representation/value of that time, same with acts of service. What I'm afraid of is mindless gift sharing in this highly materialistic day and age being mistaken for the former and the all too common entitlement of feeling one is owed a reciprocal exchange of goods.
