At random times throughout days i become distant from ppl, annoyed at the little things and drawn into my own world , should i be worried?

Your man-cave: Some people say that every grown male human needs to spend time in his "cave", alone to gather his thoughts rather than interacting. A savvy woman learns to leave the man she loves alone when he needs it. A savvy man learns to say, "i love you, please let me be for now", and when he's back to be with others, communicate effective and learn from others. Worry only if others worry greatly about you.
