It you only dwell on your past and mistake of others, you will soon get into depression. Man, it TAKES COURAGE to forgive and forget !
There are lots of reasons for interpersonal issues. Communications are one big evil. I suggested you to talk with those you have problem with DIRECTLY, reconcile if you can, otherwise move on !
Spreading negativity here or anywhere WILL NOT make you look mature , or help anyone either. You will simply give people a feeling that you were like a kid ranting out after losing your toys , but did not know how to manage the emotions and conflict, so you kept on blaming , and talked badly about his younger brother....
Man move on !! Don't dwell on the past !!
做法有問題? no one perfect. 內部糾紛? move on啦
