lol I think there have been threads like this before, maybe do a search if you are interested..
I think there's nothing wrong with being asked if it's genuine and if the person is someone you can trust and confide in, if they are someone who'd freak out or start suggesting things that you wouldn't like etc or nag or 'advise' too much so that it would be uncomfortable, yeah, then it could be awkward.. If they just expect a 'yeah' in order to feel better and don't want or wouldn't be capable of genuine communication, then yeah.. I sympathize..
Maybe people sometimes feel guilty or don't know what to say, so they just say the 'fillers' just to say something.. (my dad can be like that) Then they may think they did their parental obligations or whatever..

Maybe sometimes they are also just bored and may want some attention.. (so maybe you can turn it around and ask about them, how their day went etc?)
I think if you're genuinely happy/feel good, you can often just shrug off or laugh off stuff like this.. If you're sort of half-half (and it's maybe early in the morning), it can go either way...
Metal, maybe you listen to too much metal?

And the siggy doesn't seem particularly cheerful eh?
We can have different standards of what is 'fine' and other people can see us differently.. my mum frowns a lot and I often think she's in a really bad mood even if she says she isn't, so hmm.. (she's had some anemia so that may be a factor too..)
You could maybe also just say something joking like, 'Nah, just practising my 'evil eye'' or something.-..?

Depends who you can say it to hehe.. (if parents are super-religious maybe not

)
