At Trader Joe's this week, two young girls (about ages 10 and 8, I'd say) walked up to the freebie-snack treasure chest at the front of the store and asked permission first before they took said freebies.
Yes! A child asking politely! Yes! Yes! (fist pump into air) I love these kids and I love the parents who are teaching them good manners!
You rule, polite parents!
