I find communication is a two-way street, and I just try not to associate with passive, indecisive dumb-fucks, as then it turns into me making decisions for everyone and them usually holding my decisions-on-their-behalf against me at some point.
The nice thing about not having dumb-fucks in one"s life is they have the balls and smarts to actually like things, want those things, and then find the capacity to formulate such desires into language. So, when they say "I"m not sure what I want to eat" you can trust they literally just aren"t sure this time, and aren"t just being passive-aggressive, weird, manipulative or socially retarded.
It"s nice knowing when the Gee-Ef says "I"m not sure what I want" I can trust she means it literally, and isn"t really trying to say "I know what I want but I"m not going to say it because I want you to guess and I really have other emotional issues bubbling under the surface that I can"t find ways to resolve so I"m manifesting them in basic interaction." Or worse, if they"re really saying "I"m a passive, indecisive dumb-fuck and will never, EVER know what I want and I"ll need you to do everything for yourself AND for me because I"m emotionally stunted or have some bullshit psychological issue that I use as a crutch and means to never have to act or think consciously."
Of course, good point with family, as I try not to just eliminate them from my life just because they can be dumb-fucks. At which times, I"m thankful to at least be not-a-dumb-fuck enough for both of us, so when my mom NEVER has a suggestion for where to eat, I know the things she likes to eat and places that she can stand and am able to suggest something she wants, just doesn"t know she does.
Especially if you"re in a relationship, though, nip the "I dunno, what do you want to do" shit in the bud. It gets old and becomes a drag. And if the other person can never, ever, under any circumstance seem to make simple, basic decisions, much less just suggestions, trust that when it"s time to make a big, life-altering decision, they"re going to take the same passive route and you"ll have to make it, and since it DOES matter to them (just like it does matter where you eat!) it will be held against you.
Basically, if you"re with someone that can"t take responsibility for even SUGGESTING a potential place to eat (or the like), they"re either: 1) afraid of taking responsibility and never will, even when it"s vital they do (so, what, when you"re in a coma and the doctor is asking what your wishes were in such a situation, is your S/O going to say "I dunno, doctor, what do YOU want to do?") or 2) they"re fucking retarded or damaged and obviously can"t interact on even a basic level (worst case scenario is the ex girlfriend who didn"t want to ever suggest somewhere to eat because she was afraid we"d go there, it would be the "wrong" place, I"d get angry at her for suggesting it and hit her.... woah, red flag, eh? I was just hungry!).
If a woman can"t ever decide where you"re going to eat, that shit needs explored and fixed, or she needs to be dropped. If you, as a "man", can"t ever decide, then pretend you had a daddy around growing up and grow a fucking pair. Two normal, even remotely healthy people can figure out where the fuck to eat together, or shouldn"t BE together.
