Because just like you this person is still maturing therefore they can either be very deceiving to the eye or a very bad experience that may bring you down real hard.i have seen this happen so many times to so many people around me. however, once in a blue moon a good friend hops along but then we fail to realize and let that slip away . ending up only to sit down and cry like a baby as if time will replay on its own.i know cause i have done that once.
never mind about that i will continue with my life now so people have a lovely day.
