Reasons why I keep things to myself, #435:

When you tell people things, they learn about you. Then they can use this knowledge to their advantage. This can be very bad, and leads to them strutting around and having way too much fun at your expense.

Of course, some people don't see this as a bad thing (i.e., my friend who enjoys having his hair pulled, whose hair I pull on a semi-regular basis), and realistically it probably isn't, but damn if it isn't frustrating anyways.

Note to self: Visit local library to borrow books and pamphlets on how to put myself out there so I'll get some. Thanks for the tip, R. ;)
