delighted

You can use the adjective delighted to describe being really pleased or happy with something. Maybe you would be "stoked" about getting backstage passes to a concert, while someone getting backstage passes to the symphony would be delighted.

Delighted might be a slightly old-fashioned way to show excitement or enthusiasm, or maybe it's a more refined way to express how you feel. Saying, "Oh, I'm so delighted you decided to come!" was once a common way to show how happy you were to see a friend. More contemporary uses might be sarcastic, like when you hand your mom an armload of stinky gym clothes without a "Please" and she says "I'll be delighted to wash these for you!"
