Just lying in bed getting ready to sleep, a not very close relative suddenly called.

He said: his son had hit someone with his car, and the situation was a bit serious.
I initially thought he was asking for money.
But then he continued, after all his son just graduated from university and still needs to take the civil service exam, he can't have any stains on his record, and asked if I could cover for him?
At worst, spend a few days in jail, and he would be grateful for my help in his lifetime.
I suggested he go through legal procedures.
