Home contents insurance, do I have to have it?

I do without household insurance and nothing has ever happened to me.

Many say that, and when something does happen, the outcry is loud. Especially in an apartment building, for example, water damage can cost a lot of money.

Not necessarily. But if damage occurs and others are affected, then you have to pay. That can be quite costly. With liability insurance, you are on the safe side and it doesn't cost a fortune.
