We won’t spend much time on this, because it’s not as if you need to be told how to approach a family member or a friend for a loan. Just know that it won’t be pretty. It may be a conversation with a lot of awkward pauses. It may be humiliating. You may be told no.
It may be your only option. Of course, if your friend or family isn’t nearby, where they can hand you cash, and they end up sending you money via an app, keep in mind that you may not be able to get money from them today.
