Weakest link

This chain was originally as thick as my finger and now it's hardly thicker than a needle. Keeping a buoy at it's place for more than a decade, this chain finally had to give up against stronger forces. It was slowly eaten, not by salty seawater or hungry algae, but by constant waves that grinded it against the soft sands in the seabed.

We have arrived to our parent's summer cottage, first time this year.
