Jewish people aren't, categorically, different from anyone else - when offended, we act just like anyone does, getting mad for a while and (hopefully) coming to forgive that person in the end.\n\nOur religion teaches us to forgive - on Yom Kippur, which is the Day of Atonement, we explicitly seek for forgive everyone who has wronged us, and pray that they will forgive us. The rabbis teach that praying to God for forgiveness on Yom Kippur seeks forgiveness for sins against God - failure to keep the sabbath, taking His name in vain - but forgiveness for sins against another person only comes when that other person has forgiven. So, we seek to forgive those that have hurt us, so that they may be completely forgiven for their wrongs.\n\nThere's a parallel to most other religions I can think of - while the greatest teachers of peace have learned to forgive their enemies even in the moment that they are being harmed, those of us who can't are still taught to forgive as much as possible, and called on to remember where we nurse grudges and let them heal.\n\nHope this helps.
