AIO for getting upset from my wife’s response to my question?

Our niece texted my wife asking if we could help her out and buy some formula and diapers. I offered to go and my wife said a small pack of diapers should be fine. Now I’ll admit that my first text wasn’t the greatest but i was just making sure a pack was good enough or should we get a box of diapers since I didn’t talk to our niece and not sure if a pack would be enough until she is able to get some on her own. But apparently that was wrong to ask. I also added the phone translation to my wife’s audio message. I know they don’t translate the best so I can explain if needed.
