Today I'm wondering...

Why do people push the ones they love away repeatedly and then proceed to be angry when the distance builds? Why do people extend themselves far beyond the capacities that they are capable of, only to be unavailable for real and true relationship obligations? Why do people need an "expert" to tell them what is right in front of their face? Why is a mirror or a best friend not enough to show people that  they are enough, they should take care of themselves, they should do better? Why is it that when people say..."I get it now" they don't necessarily?
