For me, if you know your partner needs/wants something but instead you give them what you would want it's pretty pointless. It'd be like ordering my husband's pizza with mushrooms even though I know he doesn't like them and then feeling put out because he doesn't want to eat it. I mean, I love mushrooms on my pizza. What's his problem?
Myself, I'm very verbal and my family is very verbally so I need the words. I like and need hugs, too, but the words mean something to me that hugs don't.
Edit: FWIW, my INTP has become pretty competent with the verbal stuff, just like I've learned to scratch his back and play with his hair. I mean, how much does it cost to make a little gesture of affection or appreciation? I can read a book and play with his hair. He can take his shoes and jacket off while telling me he loves me. It just doesn't seem like a herculean effort compared to the pay-off to me.
Yeah.. I view it similarly. I feel like if I know my partner values a certain love language, I'll bend over backwards to use that language, add that to be a much bigger component in my repertoire. I can't easily comprehend the other person not trying to do the same in return. And if they would flat-out refuse, saying insisting it's 'not them', or they can't, what do I do with that? Should I just decide to make it tit for tat, then, and stop speaking their language?

Anyway, I think it's completely reasonable that if one persons' love language is verbal, and the others' weakest and least valued is verbal, that the latter person may not easily remember to try to be verbal on occasion, and I don't think the latter person should have to start saying 'I love you' every day or even super regularly. But I don't think it would kill the latter person to say it occasionally, if for no other reason than because they truly do love the other person and know the other person needs to hear it sometimes, as 'irrational', meaningless, or unrelatable as it may seem to the latter. And without that attempt at extension, I would be hard-pressed to believe they actually did love me.
For myself, I don't know that I need to hear the specific phrase, but some sort of similarly-messaged phrase indicating expression of emotion would be desirable on occasion.

Just to be told every now and then that the other person cares for me, I'm important to them, whatnot, would go a long way.
fwiw, I am not sure if verbal is in my top 2 or not, but I've been in a relationship with zero verbal, never hearing the phrase for 2 yrs besides my knowing he cared for me, and it began eating away at me.
