The moral of the cheng teng dessert

Last nite, my parents & i were ordering dessert during dinner when i said i wanted cold cheng teng. My dad said that cold cheng teng not worth it, because it’s more ice than the dessert itself. He said it was better to order the hot one, and let it cool down over dinner. But i insisted that i wanted cold cheng teng ‘cos i don’t like hot cheng teng!

So what’s the moral of the story here?
