am mad!!

this morn i found a carpark without effort in a busy market and i told my sis today is my lucky day.. everything went on smoothly until 11+ am, he called and we talked.. he's more to the oriental thinking and does not trust people not even me sometimes.. he was asking me whether i went out last night and i told him i didn't. i slept after text him and that time was 11+pm. thanks to my adorable younger sis, she said aloud i slept late last night and he heard that.. he didnt trust me at all but she trusted her, whom he is not really fond of.. how possible this can be? and i, the one who was telling the truth left blamed.. i am so mad with HIM and HER.. i hang up the phone and gave her a nice scold.. she didnt even apologize until NOW!! she still thinks that she has no wrong.. of course i cant blame her on everything but she knew he's very sensitive.. she should have keep her mouth shut, nobody says she's deaf if she doesn't speaks!! and that sensitive man thinks that is not his fault and blamed me for scolding him for not his fault.. i didn't receive any news form him till now which driving me crazy!! can anyone tell me who should i blame then? both sides think they're right and i'm wrong!! grrr!!
