I think we should be allowed to have limited holidays during school days. Because we might have relatives/elders that are sick in the school days. It could be an important day for our relatives like their wedding.
If an elder is sick in the school days, we should visit them. If we do, than we can help take care of them or help do things they can't do because they're ill. If we weren't allowed to visit them, they might forget to take their medicines, go shopping for new food. They might have to get up and pour water themselves and risk falling over or hurting themselves somewhere. We wouldn't want that!
If it's one of our relatives wedding and they invited us, they would be happier if we can make it. Also, if we make it, we would be able to say congratulations and celebrate with them. If we didn't, not only would they be disappointed we can't celebrate with them, we would be too! They won't want to be disappointed on their wedding day!
