Aktiviku spnjg cuti mid sem

Assalamualaikum kpd smua yg membaca. Mari kita sama2 ikuti kisah cuti mid sem sy yang pertama di UiTM Segamat. Pada hari Sabtu dan Ahad, sy hnya kluar rumah utk pergi ke majlis perkahwinan anak kawan-kawan ayah dan ibu sy. Keesokan harinya, sy pergi ke majlis reunion pelajar2 Sains tingkatan 6 di Summit Parade ( pusat membeli belah terkemuka di Batu Pahat ). Sedang sy merehatkan diri selepas penat berjalan, sy mndpt panggilan dr ibu sy yg memberitahu bahawa adik sy akn ditahan di wad Hospital Batu Pahat kerana demam denggi. Ibu sy berpesan kpd sy utk bersiap sedia kerana sy yg akn menjaganya pd mlm tersebut ( aduh, tak bestnya kna tido hospital.) Sy terpaksa menjaga adik sy di hospital selama 2 mlm ( bosan tau tido hospital. Jd, jga la kesihatan anda agar tak kna tido hospital. Hehehe…). Keesokan harinya iaitu hri Rabu adik sy tlh dibenarkan keluar ( huh, nasib baik. Kalo tak, kna la saya tido hospital lagi.). Pd tepat jam 6.30ptg, sy dan smua jiran2 sy diminta keluar dr rumah kerana rumah2 kami akan di ‘forging’. Habis semua brg2 dlm rmh sy berminyak. Selepas selesai sesi forging di rumah sy, sy dan keluarga terpaksa menumpang solat magrib di rumah saudara sy kerana rumah kami dipenuhi dgn asap dan makan di kedai mkn di Tasik Y ( pusat riadah yg terkemuka di Batu Pahat ). Pada mlm tu juga kami sekeluarga mengadakan gotong-royong membersihkan rumah dan barang2 kami yg berminyak akibat dr forging tersebut. Setakat ini shaja rsanya crta st sbb dah tak ada bnda menarik yg berlaku sehinggalah hri Ahad yg dinanti2kn utk pulang semula ke UiTM Segamat yg dicintai.

Kpd semua yg membaca, terima ksh krana sudi membaca. Yg baik dtgnya dr Allah dan yg buruk dtgnya dr diri sy sndiri. Yg baik jdkn tauladan dan yg buruk jdkn sempadan. Selamat kembali meneruskn perjuangan anda msg2. Assalamualaikum…
