Why I explain every small decision I make
The pattern, in five beats
You order tea instead of coffee and immediately add: because I already had two coffees. Nobody asked.
The word that arrives before it's asked for
You say you're leaving at 5:30 and add because I have a thing tonight. You pick the movie and specify because the other one scares me. The because comes out on its own, stitched to the sentence, before a face across the room has had time to raise an eyebrow.
It's not that you're being asked to account for yourself. It's that you keep the account ready, in advance, like a paper you carry in your pocket in case someone demands it at the door. The decision and its justification arrive in the same breath, you no longer know how to say one without the other.
What it protects against
There was a time, someone, a table, where choosing without explaining cost something: a silence that stretched, a question asked in a tone that wasn't really a question, a why did you do that that landed like a reproach in disguise. You learned the decision on its own wasn't enough, that it had to be dressed before it could pass.
So now, even when nobody's raising anything, you dress it up anyway. You justify a coffee, a departure time, a polite no to an invitation. The because is no longer an answer to a question that was asked, it's an answer to a question you stopped waiting for, because you ask it yourself before the air has had time to cool.
What I will not tell you
I'm not going to tell you to stop justifying yourself, or to train yourself to answer with just yes or no, that would just become another exercise to get right, another way of watching yourself.
I'll just name the second before the because, the one where you've already chosen and something in you is still gearing up to plead the case. That second is what matters, not the sentence that follows it.
Noticing it changes nothing right away. But it's steadier than a resolution: one day you'll feel it coming, that second, and you'll know what it is, before you've even opened your mouth.
