My friend said he wanted to borrow money at the end of the year and asked me to deposit it in the bank. It's the end of the year, and he hasn't called me yet. Should I call him?

I think it's better not to ask. If he needs to borrow money urgently, he asks you. Now he hasn't contacted you, which means there's no hurry. I suggest you deposit it in the bank. Although we are friends, we can't say clearly about money. Many people borrow money from good friends, and then they feel distressed. The more friends you have, the less money you should have.
