If you ever say Hi or Hello and people don’t mind you at that time, it doesn’t mean they dislike you, or disrespect you or neglecting you. You should know that people go through a lot in their lives and until they tell you what they are going through, never assume and blame or accuse them for not being who you want them to be or who you think they are. People get busy, tired and exhausted at times you might not expect them to be. Their minds get focused on so many things. Some get overwhelmed by life itself. Don’t blame yourself or rush into conclusions. Compromise a little. See things from their view point. Get into their shoes. Give them the benefit of the doubt. Trust.
