실망했어

sil-mang-hae-sseo · literally “I'm disappointed (in you)”

Situation: Your close friend went to a concert with others and didn't invite you. You want to say 'Honestly, I'm a little hurt.'

✕ What AI tells you

Translates it as '솔직히 좀 실망했어' or '상처받았어'.

Why it fails: 실망했어 judges the other person — 'you let me down' — and can sound like the relationship itself is in question. 상처받았어 is heavy. The gentle, very common word for this feeling is 서운하다.

✓ What Koreans actually say

Use 서운하다 (or 섭섭하다) for the small hurt of being overlooked by someone close. Save 실망했다 for real disappointment in someone's actions or character.

Cultural nuance, in depth

서운하다 has no single English word. It names the feeling that comes from an expectation inside a relationship not being met — not being invited, not being told news first, a friend forgetting your birthday. Saying it openly is actually a way of affirming closeness: 'I care because we're close.' Elders also use 섭섭하다 when someone leaves or a farewell comes, mixing sadness with affection. Because it's soft, it invites an apology or reassurance rather than an argument.
