You showed me you
This is a very sage way to deal with betrayals from someone whom you considered close.
Yes do agree with the fact I needed that jolt, as they rightly say some people cross our path to teach us something. I have had a friend who was very close and then withered off in my bad times, she taught me the importance of dealing with stress in the right way otherwise how psychosomatic it can be. She suffered from alopecia and I was part of her recovery journey which taught me a lot about the disease and the effects of certain thinking patterns. Most of the time such situations present themselves and involve us with them, just to teach us some “How-tos”. I am mostly not able to fathom the gravity of a situation unless I experience it myself. Empathy to certain things and situations just doesn't come naturally. I never used to emphasize with hungover people, as my reasoning was why did you call this upon yourself? Later in life when in company of some dear friends was indulgent and got drunk. The very next waking hours went around carrying a 100 kg head is when I realized, how important is to indulge in such situations and let yourself go and be in a half-dead and half-awake state, the very next day. For that duration of heavyheadedness, you swear on all gods that you would never touch alcohol. But do we really not do that?
People's interactions are such that unless you indulge in them and nurse the repercussions, the apt lesson cannot be learned. But don't we make a little altered indulgence in this matter and learn a little modified lesson as well? So it would go on unless you go under a rock and dwell there.
