ChatGPT cannot do punctuation grammar correctly even if you forced it

I asked it about how to use etc with three dots in an example followed by a brand new sentence starting with a capital letter afterward.

It told me : / In standard usage, "etc." is typically followed by three dots and then continues with a lowercase letter. If you are starting a new sentence, you do not add additional dots after "etc." /

Then I begged it to give me an example of that rule. One such as:
I love swimming, soccer, etc... I also love eating animals.

And it just couldn't do that. It kept typing 4 dots or single dot or no dots at all, and it can't even recognize what it typed every single time. Lol try it yourself
