actually... I have certain acceptable levels as well, but they're not always even or multiples of five... I usually do 11, 13, 15, 17, 19, 22, 25, 28, 30, 33, 35, 37, 40 and usually no higher than that... Don't ask me why these numbers... 😅 they just feel right for some reason... 🙈 but I have the same reaction when someone else adjusts the volume to a different level...
