I really don't want to go to my grandpas funeral because it's messing with my week.
But it's important. Do you have important things planned for the week?
Yeah, I have exams in the week
Funerals don't always happen at the best times in our lives. Your grandpa probably meant a lot to you and you need to go to his funeral. Talk to your teachers about possibly making up the exams at a different time.
Ugh, I don't want to deal with this right now. I would rather just stay at home.
I understand the frustration and stress, the same thing happened to me in high school with a huge trip. I had to skip out on it for the funeral, and I'm glad I did. It's a once in-a-lifetime thing, and it's super important for everyone and it's respectful so it's best for you to just go.
