Very odd indeed, though apparently harmless. The term 'introvert' may apply here and it doesn't sound like they get out much.
Good luck on your future. Take some time to re-awaken yourself and get intimate again with the things you enjoy most in life. Spend some of your most valuable time on yourself, you'll appreciate every epiphany and step forward you make. Be awesome, be good to yourself! :D
