Sassy flight attendant: In the event of a loss of cabin pressure, oxygen masks will be released from the overhead above your seat. After the screaming subsides, please place the oxygen mask around your nose and mouth. If you are traveling with a child or an adult who is acting like a child, place your mask on first before attempting to help put theirs on. –Flight out of LaGuardia
