How many days after loans overdue, will you call your relatives and friends?

Generally, if you are overdue for one week, you may repay your relatives and friends, and you may be asked to repay as soon as possible. I have never used a loan, but I have always borrowed money because I think the amount there is higher and the next payment is faster, but it is said that there will be no violent collection. After all, it is a regular big brand.
