Crazy/Drunk Girl On Board

Such a bizarre weekend.Yesterday,there was a shooting and filming going on my flight.On today's flight,another amusing incident happened.We were welcoming passengers from Yangon when we met Miss X.At the beginning,Miss X seemed normal to our naked eyes.Before we took off,she complaint that she was really thirsty so one of my generous colleague gave her a whole big bottle of mineral water instead of a glass.After that,she came into our galley again with her mouth covered as if she were about to throw up,so I quickly showed her way to the lavatory.My colleague sworn,"If she ever dares to puke in my galley,I'm so gonna kill her!".We took off peacefully until it was time to serve lunch.Non of us were in the galley as all of us were busy attending our cabin-full of passengers,but when one of us did,Miss X was caught red-handed taking all of our stocks of dry stores such as packets of Milo,biscuits,peanuts and sweets,putting those in her bag!When my colleague questioned her,she giggled and tried to kiss my colleague on the cheek!After our service ended,three of us started gossiping about Miss X's bizarre behavior.As we were talking,she dashed into the galley in a very drunk-like motion and collapsed on the floor,conscious.I held  her,but she quickly hugged me and started crying in my arms.While crying,she murmured "Mama...papa...".I shot her a weird look and when she looked at me,she started laughing saying "You ladies are beautiful!I love you all!" .My supervisor and I escorted her to her seat and tried to figure her out but she wouldn't release any helpful information,so we monitored her from far.At her seat,we saw her scratching her her head like a crazy person,lying her head on the shoulder of passenger next to her,laughing alone with her skin flushed in red.We decided to strap her to her seat before she started disturbing other passengers other than the one next to her.When we reached KL,we handed crazy Miss X to three airport security guards whom had been waiting at our bay as we landed.Before Miss X's incident,I've dealt with another nut case from Seoul whom purposely dropped her skirt in the cabin while throwing her discs one by one like a Frisbee to passengers around her.I still wonder why girls with no history of mental disorder went nuts on flights.Was it the pressure of being 35,000 feet high up in the air?
