blog comments?

i may have asked this before (or i just might have meant to) but how do you read someones comment on your blog? like under a post it will say you have a comment and have a little green dot so i click on the dot (as thats the only place the arrow appears) but get nothing. 🤔 feel bad bc dont want anyone to think i'm ignoring them (anyone who really knows me out here prob realizes by now im a freakin lost cause when it comes to technology..blame my dad..still wont buy a DVD player! lol) so maybe it's understood of i dont respond its bc im incapable.. will have to hire veenas kids as they could probably re-program my laptop while i can barely post a link.. 😳 😉 so..any tips? 🤓
