The audacity of that lad... '''I don't know'''.
“I realize this is dumb but.. Do bees.. breathe..? Like do they have tiny little lungs and stuff like miniature humans with stingers and wings? I realize I could google this, but tbh I'm a little embarrassed I don't know this already... I'd assume they either have lungs or whatever, or they get oxygen molecules from drinking water...? I dunno”

I have been chatting on other apps and I think I'm starting to develop feelings and I don't know what to do. How do Australian flesh daters do it? It's so complicated.”

Pigeons are using into it for water, or bathe in. Then they poop in it. Lots of poop. I hose it off into the grass (I am sure the grass is thankful). I don't know about you but I prefer not to swim in or drink poop water. Why do pigeons do this?”

I was going to immediately opt out as they'll likely get my data but I don't know if it's actually worth doing the surveys for the vouchers. Does anyone have experience with this? Thanks”

Comments
Used to indicate that one is speculating (often used sarcastically when stating the obvious).
Maybe you could, '''I don't know''', directly talk to her about it instead of complaining to me for once?

Used in response to a question or command in which the target person does not know the answer to or how to respond.
I don't know means: Used in response to a question or command in which the target person does not know the answer to or how to respond.. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. If your teen uses it, context will usually make the intent clear. A short, curious question about where they heard it is usually all that is needed to know whether to follow up.
I don't know means: Used in response to a question or command in which the target person does not know the answer to or how to respond.. Register: neutral, standard English. A common learner mistake is using the word in a register it does not fit, or assuming a single global meaning; native speakers immediately notice when slang appears in formal contexts, so always check the surrounding register before producing it yourself.
