If a Tree falls in a forest and no-one hears it, does it make a sound?

And if two people share a kiss that no-one sees or hears about, to the rest of the world it never happened. Lies and secrets are frowned upon in this culture, yet is it not these lies that make things work. A malicious lie designed to hurt someone is obviously avoidable, but a lie to save a marriage? a lie to save someones life? can these be so wrong. I've been considering this and I believe that the lie is only wrong if you get caught out, so many people lie on a daily basis and all they are doing is using tip-ex to cover their mistakes. Nobody is perfect and maybe a little space for error is needed, that little lie that makes him still seem perfect or makes her all the more attractive, the one that makes her feel popular or makes him interesting to the girl he dreams about. Lies may set a false precedent but  I'd be lying if I said I didn't use them each and everyday.
