If you have some sort of close confidant, never EVER take them for granted. One day they may notice the lack of care and interest and start feeling like they’re just an intellectual whore to you, and they will withdraw as they struggle to nurse their wounds and heal. Then one day you’ll need them, and you will wonder why they aren’t as eager to help you out or listen to your woes, because of you not being there for them too many times. Or, in some cases, maybe you were so busy pursuing other people, that you totally overlooked them as someone worthy of your attention.
And they might not be there when you finally wake the fuck up. That is, if you ever do. Sadly, in today’s world, friendships are very disposable.
