she teaches maths in a high school.there is often a gossip that one of her fellows,a physically strong PE teacher frequently goes out with her.i was not convinced of the gossip until i caught the man touching her hand in their office today. apparently they didn't perceive my coming! to avoid embarrassment i went straight home on my own,grieved and indignant.i should have picked her up from her work.she is still not home now.just now she called me saying that she is busy with her students' test paper.i know that she told a lie!she must be dating with the man!how come she betrayed me???
