We often confuse adjectives that can end with -ed and -ing.
We use -ed when we talk about how we feel about something.
I’m tired of my new job. (That’s how I feel)
If I want to tell you what makes me feel this way, I use -ing
Working late hours is tiring.

My brother is boring. (I’m describing him, he’s a boring person)
My brother is bored. (I’m describing how he feels right now)
Let’s practice it with a few examples:
What makes you bored and which events in your life were boring?
