I want to like a YouTube comment so that the number of likes change after I am done.
Why do you want the numbers on youtube to change?
I don't like the current like numbers, they are a bad sign. I can add to it and change the number.
It's a harmless action, so it's okay to do it. Just don't let these superstitions get too out of hand though, it's nothing to get worried over. Numbers are completely harmless.
Am I being too dramatic and can't accept these things?
The number will likely go up on its own and no number is lucky or unlucky. You need to stop putting thought into numbers like that.
