I think personal hygiene items like toothbrushes and razors shouldn't be shared. They can spread germs and bacteria, which might cause infections. It's better to keep these things to yourself for health reasons.

Personal information like passwords and bank details shouldn't be shared. If someone else gets this information, they could use it to steal your identity or money. It's important to keep this information private.

I think clothes aren't good to share. Some people worry about hygiene, and clothes can have smells or stains. Plus, everyone has their own style and size, so sharing clothes might not work.

Food and drinks shouldn't be shared without asking. Some people have allergies or special diets, so sharing could cause problems. It's always polite to check before offering food.
