Write a letter to your brother advising to him be serious about his studies
Hey Tuhin,
Hope you're doing well. Sending you lots of love! I heard something that's been bothering me. I found out you haven't been studying regularly and you're hanging out with the wrong crowd. It really makes me sad. You know our family's not doing great financially, and you're like our shining hope. I just wish you wouldn't make us feel so upset. Time's valuable, you know? It's important to focus on your studies and take them seriously. I really hope you'll listen to what I'm saying.
Take care and say hi to Mom for me. Give the little ones my love too.
Warmly,
Naimul
