I went to the school orchestra concert last night and this guy there i know, somewhat a friend, gave flowers to his girlfriend who played in the concert. Afterwards we, his older sister and her boyfriend, another friend, and me, are all outside and they start flirting and acting like an old married couple. Now i know they think they will get married eventually, their parents' ideas that they have told them, but they are only 14, 15 in a few months. My problem is the whole scene made me want to puke, but I don't want to be insensitive. Any help or advice? Thanks.
