Candy comes in many flavors. Some taste like fruit. Some taste like flowers. Some are chewy, like taffy (太妃糖) and gum. Hard candies are, well. hard! So, they last a long time.
But, in spoken English, there are some types of candy that you cannot eat. For example, you can't eat eye candy. Eye candy is a person-man or woman-who is very good-looking. So, looking at this person is a treat for the eye, just like candy is a treat for the taste buds.
Do you hear of candy coat? Of course it is not a coat made of candy. But you can say I don't candy coat the truth. What does candy-coating something mean? Well, some pills are covered with a coat of thin, sweet candy. The coating makes swallowing the pill easier, and it may hide a bad taste. So, candy coating a difficult truth or situation means you don't directly discuss its bad parts.
After talking about candy you may want to eat some candies. However, some people dislike things that are very sweet, especially adults. But even if you do not like candy, you can still be called a kid in a candy store. This expression means a person is very happy to do something or to simply be somewhere. Imagine a child going from one candy display to the next, not knowing which candy to choose!
Talking about children brings us to another expression: as easy as taking candy from a baby. Think about a small, helpless baby holding a piece of candy. Taking it would be very easy—mean, but easy. So, use this expression when you are talking about something that may be simple to do, but probably not right.
