Idiom: Be the apple of someone's eye
Meaning:  Be loved very much by someone; someone's favorite person or thing; a boyfriend or a girlfriend.

If someone is the apple of your eye, you think he/she is very important to you, and you love him/her very much.

This idiom is used especially when someone is loved by an older member of his/her family. 

Examples: 

• Kelly is Bob's only granddaughter, and she's the apple of his eye.
  
• Sarah's only son was the apple of her eye.

A common mistake of Hong Kong people is to say "I am boring" when they mean "I am bored". 

Does it make a difference?  Of course it does! And you may get yourself in trouble if you mix these two sentences up! 

Remember:

Adjectives that end with -ed talk about one's own feelings, whereas adjectives that end with -ing talk about a person, a thing or a situation that causes one's feelings.

For example:

• The movie was boring (so I felt bored).
  
• This book is so interesting (so I am interested in the book).
  
• My boyfriend has a very annoying habit (so I am annoyed)
  
• English usage can be confusing (so a lot of students are confused).
  
• My husband's job promotion was surprising (so we were very surprised).
  
• The baseball game between the Giants and the Tigers was exciting (so the fans were excited).
  

Idiom: Grab a bite (to eat)

A tongue-twister is a phrase that is designed to be difficult to articulate properly, and can be used as a type of spoken (or sung) word game. Some tongue-twisters produce results which are humorous (or humorously vulgar) when they are mispronounced, while others simply rely on the confusion and mistakes of the speaker for their amusement value.

Tongue twisters are lots of fun and difficult to both native and non-native speakers of a language. They often don't make much sense, but they certainly exercise your pronunciation muscles.
