There's always a truth behind just kidding, a little emotion behind 'I don't care', a little pain behind 'it's okay', a little 'I need you' behind 'leave me alone'. And a lot of words behind the silence.
"In the end we only regret the chances we didn't take." So be risky because you would rather look back and say I can't believe I did that instead of I can't believe I didn't do that. I do regret that amazing chance that I didn't take.
