or did this decision happen in a different, more natural way? (If so, an explanation of the way this decision happened would be appreciated)
the best analogy i can think of is this: what made you decide to use the word "to" in your question? you probably did not make any conscious decision to use that word, but the word got used by you nonetheless. can we explain why? maybe not...... it's probably buried somewhere in the part of the brain that knows how to make things up
