A difficult to see comment of yours above?
Why not add an empty line before and above your comments?
Are you trying to make them hard to find?

Another hard to see and find comment from you. Why? Why not
take the extra care and diligence to add an empty line before
and after your comment, so that it is easy to see? Why do you do this?

I think it is "generally" unaligned coming from you as you can
see in the reviews in this list. Configure "vi" or use something
else, "Emacs", etc.
