Adjectives ending in “ED” and ”ING

We use adjectives ending in “ING” to describe something or someone.
Examples:
Maria is watching a very interesting movie.
I hate that teacher. He is really boring.

We use adjectives ending in “ED” when we want to describe how people feel.
Examples:
This movie isn’t interesting. I am bored.
Juan is very exited because he is going to travel to Miami for the first time.

Conclusions
We can use adjectives ending in “ing” for things or people. Remember that when we use “ing” it is describing the person or thing.
We can use the “ed” ONLY for people (or animals) because THINGS CANNOT FEEL.

We can say:
Felipe is boring. (describes his personality).
Felipe is bored. (he feels bored at the moment)

We can’t say:
The TV program is bored – INCORRECT (because things can’t feel).
