~ to take a risk to suffer cold is better than people who keeps the troop unmoved ;
~ thank you for seniors' comments educated, as matter of fact, where there is smoke there is fire, good laws without capable law enforcers are useless, half a loaf is better than no bread
~ have a nice day ;

外國人雖很講禮貌但並無好似中國人在飯前「叫人食飯」，這麽做反而令他們覺得奇怪。他們會等對方的食物一同上枱，但很少會叫你先吃“take your meal first”。

若你堅持要飯前要「叫人吃飯」，你可以話“I hope you will enjoy your meal ”

A XX, A XX, meals

The food that is eaten at a meal (dinner) at home:-
=Enjoy your meal !!
=What do the kids have to say to foreigners to listen !!

Go ahead please!
Feel free to eat!
