*Warning= anak siswa ditegur karena berkelahi jadi dia disuruh panggil orang tuanya( children students reprimanded for a fight so he was told to call her parents) *short notice=pengumuman libur sekolah,pengumuman hasil ulangan( school holiday announcement, the announcement of the results of repeat) *sign=seorang siswa ditandai karena dia berprestasi di sekolah,dia ditandai karena bikin kacau disekolah ( a student is marked because she excel in school, he was marked as messed up in school)

Warning!!
Throw the rubbish at the dustbin.
