i hardly ever volunteer information about myself, with the exception of things i'm really excited about like recent accomplishments or upcoming events. however, if someone asks me a question, no matter how strange or personal it is, i'll answer it honestly, with the (recently acquired) exception of AS... i haven't decided if i want to go public with that yet.
i am very secretive about my personal activities. it makes people assume i am hiding things. i don't like people in my room when i'm not there or touching my stuff or even knowing what i am doing most of the time. but if they ask, i'll gladly fill them in on the details.
i think that might be related to my fear of boring people. if they ask, i know they're interested... but if they don't, i keep quiet for fear of scaring them off with excessive (but in my mind, necessary) details.
