This is my DS's explanation for why he hasn't eaten the olives I've put in his lunchbox.
Deeply peeving, as he's such a fussy little sod and olives are one of the few vegetables that he will actually eat like sweets. Until now. He'll eat them at home all the time, but at school, what's obviously happened is incredulity from other kids which has made him self-conscious about eating them.
What a PITA.
