Is OTHER wrong in the post ? POST : Apologies for being on mobile in advance and any formatting errors that follow.

A few minutes ago, my boyfriend and I got into a discussion about how he thinks it's rude I don't ask people how they are as he considers it a common courtesy. The reason I don't is often I feel it's unfair on the recepient if I ask how they are, then simply feign interest whilst we have a dull conversation about how they're fine. 

Most people I'm close to care about will outright come to me if they have anything of import/interest to tell me rather than expecting me to check up on them every five minutes. My boyfriend despite this things its just the right thing to do, however it's clear lots of people really don't care... Take the other day - he passed by someone he knew when we were leaving his flat and the conversation went as follows:

Bf: hey you alright mate?
Friend: you all right?

They didn't say it at exactly the same time so it wasn't as if they accidentally over spoke each other, neither actually responded, and then they both just walked off. Am I crazy for thinking this is just a tad bit pointless? Either way, he refuses to get into a conversation with me about it as it drives him mad, so here I am.
