Sara's advice for travelers...
#1 Check your child's pencil bag to make sure the scissors were removed
#2 If you buy perfume in duty free, put it in your checked bag once you clear customs and before boarding your connecting flight.
#3 Know the ounces in the perfume bottle to make sure it's over 4 oz. and not 3.5oz. before surrendering it to TSA
#4 Never try to reason with airport personnel, they all failed Interpersonal Communications.
#5 Most importantly, when travelling abroad, check all possible VISA requirement and possible scenarios that might alter your travel plans. Especially because you will realize too late that you were actually supposed to gain clearance.

As we live we learn, as we learn we grow, as we grow we become smarter! (maybe)
