Be it your personal life or otherwise, online or offline, we deal with all kinds of people and issues.
When trying to complete a task/project/etc. we want things to go and get fulfilled in a certain way but if Allah wills otherwise that we get annoyed at the person we are dealing with, rather then trying to resolve the issue at hand and trying to get the task/project/etc. done. We make people issues and everything becomes about I and you and fault rather then the issue at hand.
Inshahallah next time we fall in a situation where there is a conflict/issue we can focus on resolving the issue rather then fixing the blame while learning from our fast.
Everything comes from Allah so pointing fingers and blaming doesn't help. As a Shaykh once said when you point one fingers at other four fingers are pointing at you.
