Nothing will mess with your head like being in front of someone you used to be so close with, then turning and walking away without saying a word. Someone you used to spend hours with, talking and laughing, maybe crying and hugging, sharing all that life brings you with this person, and you have absolutely nothing to say to them anymore.
Rather there was a big event that caused your relationship or friendship to come to a breaking point or life just took its toll on you; it is so sad to think about how close you were with someone.
Rather you are parked at a stoplight next to them, run into them in the grocery store, encounter them with mutual friends at a gathering, or simply just see them from a far at an event, the best advice I can give you is to kill them with kindness. Sometimes life's unexpected circumstances or misunderstandings put you in a place to be mean or nasty to someone and think you are entitled but truly for you and for everyone else's well being the best thing you can do is let that grudge go and give that person nothing but kindness.
I am in no way saying that you should allow someone back into your life if they have wronged you, or allow someone a second or third chance that maybe does not deserve one. I am saying that you should allow yourself to be freed from the burden of hate by simply just waving or asking how they are doing. It allows so many positive affects on yourself, not only on them.
Maybe losing you in their life was just as hard, even if they will not ever admit it or do not care to express it, maybe you simply saying hi could change their outlook on life and remind them to hold on to people that are good to them.
If the worst thing someone can say about you is that you were good to them but you respected yourself enough to walk away from a toxic situation, you are doing alright.
SO... This is your reminder to let the hate of the past go. Do it for yourself, do it for them, do it for those around you, but do it.
Kill everyone with kindness, no matter how they have wronged you.
XOXO
