I have a relative staying over right now and he has to have an opinion on… everything. Examples:
“That’s a nice watch… How much did you pay for it? That much? That’s too much money”.
“That meal looks good… You should add some cheese to it”
“What size is your bottle? Don’t you think it’s a bit large? it would be better if it was smaller”
“That would be better if they didn’t add sugar to it. They put too much sugar in it.” Me: “There’s no added sugar”. “That would be better if they didn’t add sugar to it.”
LIKE BRO???
Nowadays I don’t have this problem, but I know exactly which sort of person you’re talking about: they act as if their opinion was always important, relevant, or welcome.
For me it’s most of the time just an annoyance, except in one situation: if they’re vomiting uncalled advice on my face, because then I’ll interpret it as an insult. (EDIT: 3/4 of the examples in the OP show this.)
