5 pesan dari om hahahaha :D

1. jangan memvonis diri sendiri paling salah dan ga mampu

2. kalo emang udah ga kuat, jangan berfikir lw bodoh, tapi emang mungkin itu terbaik
3. hari berganti dan banyak hal yang akan terjadi, jadi jangan terlalu difikirkan,sewajarnya aja. karena lw masih punya tanggung jawab yang lain
4. jangan membuat cinta menyita semua waktu lw
5. rumah harus diurus


yang kelima agak menyimpang dari topik tapi okelah makasih hhahahaha :D
