Bored or boring?

Some participles (like 'bored' or 'boring') can be used as adjectives. These are used in a slightly different way from normal adjectives. We usually use the past participle (ending in -ed) to talk about how someone feels.
 

• I was really bored during the flight (NOT: I was really boring during the flight).
• She's interested in history (NOT: She's really interesting in history).
• John's frightened of spiders (NOT: John's frightening of spiders).
   

We usually use the present participle (ending in -ing) to talk about the person, thing, or situation that has caused the feeling:
 

• It was such a long, boring flight (so I was bored).
• I read a really interesting book about history (so I was interested).
• Many people find spiders frightening (so they're frightened when they see spiders).
