Off-topic: why do you tag the user whose comment you’re directly responding to? Others, sure, but the parent comment already gets a notification of your response.
This happens automatically on the web client for Mastodon when you reply to a thread. I could have manually removed yours from this one. I have mixed feelings about whether that should be default. Untagging could be construed as rude? On the other hand it can be a bore to be involuntarily involved in some seemingly interminable thread that you only meant to reply briefly to.
