erm... (free spanish course)
I have something else to say about this... In spanish we have something called
"sujeto tácito [tácito] [tacito]" which can (?) be translated as "tacit subject" or
"missing subject" or better "implicit subject". It's a construct in our language (I think
partuguese and other latin languages has it too, but english and german don't). As the
verb is conjugated for every person, we don't need to say "I", or "it". An example:
It is THE SAME to say "Yo como papas" [I eat potatoes] than "Como papas"
([I] eat potatoes). (actually the first is a little more strong, if it can be said)
The verb "como" (eat) has an implicit "I" in its conjugation. It (I) como,
(You) comes, (He) come, (We) comemos, (You [plural) comen, (Them) comen.
We are used to not saying the subject of a sentence, that may be why we consider
implicit self not so disturbing... (may IT be?)
Changing the subject (just a little)
When I first learned Logo (my first computer language) 14 yeas ago (I was 11),
I had to say "forward 20" "right 90" "repeat 10 [fw 10. rt 36]"
Who was I talking to? to the turtle, of course. was I think:
"self forward 20"
"self right 90"
"manuelita forward 20" (manuelita is a tipical turtle's name in argentina)
"manuelita right 90"
"forward 20" (looking at the triangle)
"right 20" (again, looking at the triangle)
I think (I'm trying to remeber through 14 years) the last one.
just some other $0.02
