Ughh! I got a similar response. I give out full candy bars for Halloween, and had one parent tell her kid that they could not have any because it would make them fat. Really?! So my candy bar is going to make them fat versus the rest of 5lbs the candy get while Trick or Treating. Whatever!! Also had a parent dig through the candy bowl to find something without nuts. This I can understand but still annoying.
This year I was surprised to see multiple instances of children carrying two bags, one for them and one for their parents standing back on the curb. If you could afford to get your kid a costume, buy your own darn candy!
