Time. You can't touch it, stop or control it, smell or taste it, some say you can see it and some say you can measure it - Tick, Tock, Tick Tock.
Since the beginning of time - that's a bl**dy long time ago.
But apparently, you can waste it. It's not very patient either, but, having said that it's a great healer.
It can sort things out and change things, although it's not too good with secrets as in the end only Time will tell and it's always revealing stuff.
Its a constant friend Time will never leave you alone.
Time. quite an amazing thing actually.
