Email Security
Sometimes when you register for new websites, it will send you an email with your password written right in the email. If you left your email open, it's entirely possible that someone could do a quick search and find your password.
Go into your email service of choice and do a search for common passwords that you use. If any emails show up, delete those emails. Repeat with a search of any other important information like your social security number with and without dashes. If you log chats, make sure nothing is there as well (like credit card numbers IM'd to you by family members).
