How can you do this to me?

Went to my friend's (he is my room mate) wedding reception function last month. As my friend cooks most of time for both of us, I told his sister, "He was cooking nicely for me, now I am going to miss it".
His sister gave a laugh and said "Go tell this to the bride on stage and ask her, How can she do this to you?"

On the podium when I mentioned this statement to the couple, my friend quickly replied, "Dont raise any cooking related topic now, for a while(since their engagement) we have been debating over phone who is gonna cook after marriage..."
