Just looked at the first set:
Jedes Ding hat seine zwei Seiten.
– Liza
Die Axt im Haus erspart den Zimmermann.
– fred
These are proverbs. The first one says: there are two sides to everything, meaning “there are pros and cons for everything”.
The other ones says: An axe in the house makes the carpenter unnecessary – the equivalent of “god helps those who help themselves”.
Why would they post that? I have no idea. Perhaps just bored.
