This seems pedantic, but these differences _do actually matter_ for having conversations and communicating around these sorts of things, and you and I may mean different things when we say "I."
Which gets worse when we talk about what we might mean by "to eat" and "lunch."
e.g., there's a joke running around on Facebook right now commenting on a "guy" dating a confused lesbian to find out that they are, in fact, themselves a confused lesbian.
The punchline is "well you are what you eat"
