I have different tools for different situations. My DSLR kit is with me for work, family situations, some vacation, some travel. I've a waterproof/shockproof camera (D10) for when I am in or on water, or skiiing, or where I need something that won't get easily damaged. For casual situations, I've got a G15 - small enough to slip into my pocket, good enough image quality for most snapshot/record shot situations, including family occasions, going out and casual travel. And finally, for truly impromptu shooting, I've got my cell phone which is pretty much always with me. The other aspect to the OP question, is that sometimes life does NOT have to be documented in an image to be enjoyed. In fact, trying to get the right shot may diminish your ability to fully participate in whatever's going on. Everything has a time and place, and photography isn't always what you want to be doing.
