Haii guys

Korang nak tahu something tak? 🥰
Akk just nak share some cerita/nasihat

Ramai nohh acc sunyi 😂😂😂 understandable 😌👍hahah

Sekadar perkongsian ja🤓✨

One thing I always ask myself sebelum post sesuatu di media sosial...❔

"Adakah benda yg saya tengah tunjuk ni benda baik? Atau adakah aku tengah menayangkan dosaku ?"🤔

Kalaulah aku tayangkan benda yg berdosa❤‍🔥 and then the people who look up to us think it's "RIGHT" to do it sebab kita pun buat😭nampak kecil tp impaknya besar. Kadang kita tak tahu who looks up to us😮 and without realizing mereka turut ikut apa yg kita buat. Benda ni boleh jadi dosa jariah dan akan sentiasa mengalir selagi orang lain melakukan dosa tersebut💢

So basically nasihat akk for adik2 semua is to "tapis" dulu apa yang kita nak kongsi dalam media sosial 🙈✨ apa2pun, thank you sudi baca nasihat akk yg tak seberapa ni🥰🌸
