What did I just say?

Walking along suddenly something just slightly touched my hair and I heard a splashing noise. I looked up and saw and heard some seagulls laughing. I did not want to touch my hair so I stopped the first person I could see. I asked a young man - Do I have bird poo in my hair? He looked and checked and said no you have no poo in your hair. Then I thought what did I just say to an unknown person??  That must be the most strange question I have ever uttered to someone I do not know.
