i have a friend who's always extremely busy, to the point where she doesn't reply for more than a day even though she's often online. it's been going on like this for months. i respect her time boundaries, but doesn't this show a pattern? most of my friends work and have lots of other things to do but it's never like this with any of them, it literally takes a few seconds to reply? is it naive of me to believe her or she's doing this on purpose?
