"Ha ? Costume?" was my sister's response.
"Yes, costume.. for halloween,.. remember ? It's this Saturday."
and she says "Is it this Saturday already ???"
Okay. Guess that answers my question. My nephews still do not have costumes and I am actually wondering why they haven't even reminded their mom about it - the older one is 9 and the younger one is turning 6, kids that age still go trick-or-treating, right ?
