Do you ever upvote your own comments?

I was looking over a post and was tired and accidentally clicked the 👍 on my own comment... I unchecked it when I saw what I did, but I never realized that the app allowed someone to upvote their own post. This seems to me like an odd thing to do, because if you wrote it it makes sense you would agree with it, but to upvote it almost makes it look like someone else is saying they agree too.

It's not overly controversial, I know.. I am just curious if people do this and if you think it is ok or honest?
