People come with different, sometimes even contrasting sanskars. Often, we find such people among our loved ones—spouse, parent, child or sibling. At such times will need to adjust to their nature. Adjustment is about our thoughts for them, not just our words or behaviour with them. We need to accept their nature, not question or get disturbed about them.
A person at home can be strongly egoistic and difficult to please. We give them all the love and regard possible, but that person may not reciprocate accordingly. The day you praise her, she will be nice to you. The day you point out her mistake she will turn hostile. There can be a team member at workplace expecting appreciation for every successful task. If you stop praising him or if you praise someone else in front of him, he may feel demotivated.
