Parents ought to warn their kids to the max. The punishment ought to fit the crime. Especially when it comes to OVERDUE books that belongs to the library!!
Libraries are getting more aggressive about their overdue books these days. Even when there's kids involved.
If it wasn't the threat of fines that could put kids and parents in the poor house already, it's the local jail and having a record for life already.
What parents need to do is start teaching kids the responsibility for the public books. Even returning them on time is very important. Because if they don't, bad things do happen.
Here's a suggestion for parents, buy books to keep at home for yourselves.
