どのような意味でしょうか
Fifteen years ago my sister-in-law and I had a mutual friend, Barbie, who told me something unflattering about my sister-in-law. My relationship with my sister-in-law has been fractured ever since. I have since severed my relations with this friend for numerous other reasons, but Barbie is still good friends with my sister-in-law.
Recently, I have felt that I should let my sister-in-law know how this woman betrayed her friendship by telling me her secret. Should I tell my sister-in-law or leave it alone and let her find out for herself? Seeing her buddy up to this person makes me crazy.
Seeing her buddy up to this personはどのような意味でしょうか？よろしくお願いします
