Helping a relative always sucks. You can't just say no. However, if you make a mistake, you hear about it for a long time.
My girlfriend is too kind in a way few other people are. She's always helping anyone who asks, and I have to deal with her complaining about people not paying her back or other consequences of her actions.
Anyway, a family member of a friend of hers asked us if we could help them get some money (actually, it was 1.3 million euros in cash) that someone owed them. And before I could reason with her that it was a horrendous idea to help, as there was no upside for us, my girlfriend agreed.
To my surprise, it all went smoothly. We stored the money in a safe provided by a friend's family member, who was the only person who knew how to open it once we closed it.
We had to wait a week, which was very nerve-wracking -- and of course, my girlfriend complained about it, too. We stayed home because we did not want to leave the safe out of sight. When one of us left, the other would stay.
We were sure that nobody had touched the safe.
But it was empty when the friend's family member showed up to collect their money. We quickly escaped the situation, and I'm now writing this story from some island you've never heard of.
