Can you hold a grudge and be mad with someone for them making an assumption which wasn't true and was wrong and they made comments on what they thought was right?

It's understandable to feel upset when someone makes an assumption and voices their opinion on something they are not knowledgeable about. However, holding a grudge and being mad at someone for a prolonged period of time can be detrimental to your own mental and emotional health. It may be helpful to communicate with the person and express how their assumption and comments affected you. It's possible that they didn't realize the impact of their words, and communication can help to clarify their perspective and your own. Ultimately, forgiveness can be a powerful tool in releasing negative emotions and moving forward. It's up to you to decide whether or not to forgive, but it may be worth considering in order to let go of the grudge and find peace.
