I wonder, what My dad probably said to my mom when he saw me topless at the beach ?

I am from Thailand, Once, At the beach, I went topless, and My dad too was around there at the beach but when he saw my tits, I turned red in shame and I tried to cover my tits from my hands and I moved away from there and quickly wrapped a towel, but my dad just smiled at me and he said something to my mom in her ear, I wonder, what he said to my mom ?
