In American English, a stool can also mean furniture and poop. (I am guessing this comes directly from German.)
The comment, you replied to, makes sense because in American English a stool and a chair are different types of sitting furniture. The difference being a stool has no or limited back support and can be counter height.
I miss being able to let the phone go to voicemail and being able to answer messages whenever I feel like it. Now since we have our phone with us including the toilet, people can accuse us of ghosting after sending us a text message, message us on social media, use a messenger, or email us.
It's probably me misunderstanding. Thank you for the correction.
