Question

why shouldn't we allow our belongings to be used by others​

Answer 1

Answer:

Why should not we share our personal belongings?

You can end up with a cold, a skin infection, diarrhea or any number of nasty things if you share personal stuff. Our fingers and hands can be “vehicles” for germs to hitch a ride from one place to the next. So by not sharing, you're helping protect yourself and others from these germs..
