Im glad to know that you're not taking my subject for granted and that you like my class Nice but I just cant help feeling it because most of you were avoiding me and no one even bother saying sorry. I was a student before too Nice and I completely understand your situation. All I ask is to let me know what's going on and be honest to me. A simple sorry for missing the class is enough for me but what I got is that some of you are avoiding me and hiding from me. You can't do that not only to me but to others. You have to face someone and be honest. You could get him or her angry but that's the consequence you have to face.
I hope you understand me Nice.
Find time to present your reports next week and I hope your grandfather is ok and is not in critical condition. I'll pray for him to get well soon.
P.S.
Your grammar is fine. You don't have to worry about it.
