it drives me nuts when my ESE grandmother (remember her?) tries to offer me stuff like that.

about half the time:

"do you want X?"
"no"
"do you want Y then?"
"no"
"do you want Z?"
"would you shut the fuck up and leave me alone?"
"(some comment about how rude and abrasive i'm being)"

the other half the time she simply gives me something without my asking:

"what the fuck is this? why are you giving me this? i'm not hungry. take it away."
"(see comment about rude and abrasive)"
