Airports are not only a place of welcomes and departures.
It is also a place to shop,
a place for family outings,
a place to study.

Since, it's a holiday. Airport is very crowded.
Young parents brought their children to the airport, sat there and watched the kids run about. The young mothers trying to stop their children from throwing one another into recycle bins, while their husbands daze away despite the screaming of their wives and children, and the maids carrying another little wee one.

Those husbands look like they regretted getting married.... XD

Studying at places like this is worse than studying at home. You can see that I spent more time observing people around us, more than the words on my notes. XXDD
