Short people

In my experience, it is surprisingly difficult for a tall person to position things within the reach of short people.  It just doesn't occur to me that something that is effortless for me to reach is not accessible to someone shorter than me.  I think that it would be much simpler for me to realize if I ever stored things in places that are inconvenient for me to reach, but I can grab basically anything at any height in my home other than my bedroom smoke detector.  If effort were required, I'd probably think to myself, "maybe a shorter person wouldn't be able to reach this at all," but that's not the case.
