Eye pollution

Hong kong is famous for air pollution (for those of u who have been here before, you know how the sky looks like and how the air "taste" like...) and noise pollution (cling cling clang clang, that's the noise you keep hearing in restaurants, and of coz loud people everywhere)...after x yrs in hk, i found another type of pollution in HK...you may wonder what it is...it's eye pollution~~~ hehe...been taking MTR all along, walking around HK for long long time and i guess mayb it's because of the LOooooong subway rides these days for me, i noticed more things occuring in the train.....everywhere you go in hk, you will see alot of young couple (be it the conventional type of couple or the generation x type of couple), they are quite "loving"....i guess HK is small and ppl are just comfortable with it or they just dont care what ppl think or see.....loving couple is good, they hold hands (normal), they hold waist or shoulder (normal), when they started to hug each other while taking subway or elevator (well, started to get a bit less normal but still acceptable), they then proceed to wrapping in each other's embraces in the public (ahem...a bit too much, they get some stares but quickly forget)....when they started kissing each other (hhmmm, okla...sometimes ppl are just affectionate)...but when they started to lick each other's ear lopes??? NOOooo, it's getting too much!!!!! yup, what i just described are common in hk except for the last one....today, i was taking subway and saw a couple walking in...two teenagers looking like they just started secondary school not long ago....first, they wrapped each other like they were being super-glued together...then after a while, they both sat down and the gal started to lick the guy's ear....OMG OMG...luckily the guy had a bag on his lap...then the guy returned a kiss on the ear...and the little girl did it again....ppl were watching them but they didnt seem to notice....time to get a room, man....they didnt know they were putting on free show for the public....you may wonder why i put the pic below...it's salty wet kinda of scene (AKA 咸湿）
