It is an instinct for a brother or sister to take care of a younger brother or sister.

After all, a female compatriot, blood is thicker than water, and it hurts the bones!

Of course, maybe your parents dote on your sister and make you jealous. Maybe your sister's personality makes you feel stressed. Maybe you two are not happy together. ...

Otherwise, my sister's wedding, as a brother or sister, must be the most positive and happy, and happy sister can find her Mr. Right.

Whatever the reason, your sister's wedding makes you unhappy, and you don't want to bless her, so don't force yourself, let alone embarrass your sister.
