Oh really?
Not the parent, obviously. But if you're providing for their needs, and if you're living with thier mother (and providing for some or all of her needs) and you're not being a "parent" in some form or fashion, then you're being a chump.
That probably sounds a lot harsher than I mean for it to, but dude - you've got these people in your life now. If they need some direction, give it to them and don't apologize or feel guilty for it.
Doesn't mean you gotta be an insensitive prick about it or not seek outside assistance, but hey - there's a time to lead and a time to follow. The time to follow is when somebody's got a better sense of direction than you do. The time to lead is when nobody else does. Right now, the latter seems like it might be the case.
From what I've come to know of you, not having a sense of direction has never been a problem. It's now a question of using it on an intimate group, and not just on yourself or on business associates.
Step up, and good luck.
