I'm an idiot

I am at my cousin's because it was our sister's wedding. Last night we were about to play UNO Flip, but one of my cousins went to the toilet. Now he had a number I have saved on my phone, even the recent one too. I didn't know he changed his number. So I called that old number and asked, "Kahan hag raha hai?". While I was saying this, there was a girl on the other side, "Hello," and I'm without a clue asking again, "Kahan hag raha hai, jaldi niche aa." While I was saying this, a realization hit me, and I quickly hung up.

I wonder what that girl might be thinking lol
