Heh... I had a good example last night, in fact. Back last summer when I had the appendicitis, I got all mad at my husband for not helping me out of the truck when we got to the hospital -- but he pointed out that he didn't know I needed help -- which seems kinda brainless to me, considering the pain I was in (AGONY), but I have to consider, HE wasn't feeling that pain, he really didn't understand how bad it was.
Last night, on the way home from my parents (about a 40 minute drive)... all of a sudden, I started feeling really odd, really bad; thought it was simple nausea at first, but very soon realized that I was about to pass out -- so I said "I think I'm about to pass out," and managed to get bent over enough (still seat-belted!) to get my head down... I requested that he find someplace to stop, so I could lie down in the backseat of the truck.
When we did get stopped, I realized I was not capable of getting out of the truck by myself, as I didn't want my head to hit the pavement. So, in the loudest voice I could manage (a soft whisper), I said "can you help me?" Immediately he got out and came round to my side, prepared to do exactly that. But I realized that even with his help, if I tried to stand, I was probably going down, so I just asked him to help me get the seat-back lowered, and my feet up on the dash -- and he did exactly that, and then, when I asked, went into the store and got me a ginger ale.
When we got home, he asked if I was alright to get out, and walk to the door, and I was, but he stood and watched and waited, to make sure. When we got in, I lay down on the couch, and realized I was in no shape even to warm up leftovers, so I asked him how he felt about Sonic for dinner, and just to get me some tater tots, because I badly need carbs (it was the consumption of an entire 20pz pepsi that I think led to the problem in the first place, when all that sugar and caffeine burned out, it left me NOTHING, as I hadn't eaten in about 9 hrs). He went directly to Sonic, got his foot-long coney dog and my tots, came home, I ate, then went straight to bed -- at 11pm!
He did everything I ASKED FOR, but if I had not asked, he wouldn't have known what help I needed, I would have gotten mad at him for not being psychic, and he'd have gotten defensive, so we'd have had a screaming match. Which wouldn't have helped anything. By asking for what I needed, I got it, and my husband was glad to give it -- but he couldn't read my mind and KNOW what I needed.
