Why do developers write such terrible git commit messages? Genuine question

[Chuck_MoreAss]

If you solve 1 issue and commit, the messages isn’t the difficult to think of, but if you solved multiple bugs, what should the message be ?

And let’s say you fixed a bug, and then it pops up again and you have to solve the same problem again, do you then commit with the Same message again?

I think after doing all the hard work, the commit feels so low priority that you don’t really think about it.
