What do we mean when we say...

Have you noticed the words " Horn OK Please" at the back of trucks? what is that all about?

Ever wondered about the phrase " Believe me you"? It almost sounds grammatically incorrect.

For those of us who travel by buses, you hear the conductor instructing people in marathi by saying " maage chalaa" which literally means "go behind". But since we are inside the bus, I wonder behind whom are we actually going?!!

When you has one too many ice creams, you hear the phrase "Be careful, you could catch a cold"। Why would anyone want to catch a cold and how do you do that anyway?

There is a phrase in hindi called "दीवारों के भी कान होते है". Loosely translated in english it means " that walls too have ears" and hence one must speak softly lest you let out some secrets. Well that still does not make much sense to me.
