So just to give a bit of context, I was talking to one of my friends over text about mechanical keyboard switches and which type of switch colour to get. When I told him to get brown switches because I own a mechanical keyboard with brown switches and they are good and I liked it, he told me that his other friends said not to get brown switches. So being curious to know why they didn't like it, I asked him why his friend thought of not getting brown switches. This is how the conversation went:
My friend: My friend told me not to get brown switches.
My friend: He said every time people talk about brown switches then they put this emoji 🙄
Me: What is that supposed to mean?
My friend: Means they don't like it.
What do you call someone when they don't give a reason to why they don't like something but just give something that is irrelevant that doesn't benefit the person trying to understand why they don't like it. Or maybe what kind of answer is that?
