Sugar bean square dance girl is not a fool

Is it abnormal for elder sister to hold elder brother's hand? Mainly to see if my sister was born to my sister, a mother. Of course, this is normal. Otherwise, if I don't hold my sister's hand, will it still hold my sister's hand? So it's normal. You can't say you misunderstood. Just explain to him that my sister is usually related, which is normal. If she blindly recognizes her sister outside, it is not normal. So, uh, my sister.
