You nailed it.

My funniest moment is realizing that grenades are better stealth weapons than a pistol. Someone sees you shoot a silenced pistol, you're screwed. If someone watches you throw a grenade, but you get into hiding fast enough, they don't put 2 and 2 together between the thing you threw and that random explosion.

I was in a certain important location and accidentally hit the grenade button... So without thinking I ran. Everyone but one died, and nobody was mad at me. So I looted all the corpses, and walked on whistling.

God that reminds me of almost EVERY bad day I had in Fallout games.
