great grandpa rule

Be sure to follow the rule before you head out.
Rule: You must post before you leave.
Right, it looks like there are 7 levels of comments that are hidden. The first one we see is responding to comment level 7. The 2nd comment is responding to comment level 6 (not the first comment that we see as it appears). And so on.
So it looks like nobody is actually responding to a thread that we can see.
No, Tumblr nests the original the furthest in. The opposite of places like Reddit/Lemmy, where they nest subsequent comments down. So the furthest to the right is the original comment, and each step out is a new response to the original.
