The longest grudge I am able to keep is a day. The minute I sleep on anything that I’m upset about, I get over it after a good night sleep. I just don’t have the energy or the stamina to hold and keep a grudge. It just isn’t in me to sustain anger, I’m not capable or perhaps it’s that I have not tried hard enough. Either way, I’m glad that I don’t hold grudges, life is too short.
If I don’t speak to someone, if I specifically ignore someone who I am an acquaintance of, that usually means that I just don’t care for them. Not necessarily in a bad way, more along the lines that I have nothing in common or no connection with them. But that isn’t holding a grudge, so all I can say is that I cannot and will never be able to hold a grudge.
