Florentia52, He was tired and sat down to rest and eat some food even though no one in the room asked him to have a seat.
Sometimes, I encounter phrases like 'went tired to bed' , 'lies tired somewhere', etc. on Internet. By analogy with these phrases I assumed, I could say something similar with use of the verb sit down. Do you think I should use tiredly in the second sentence?
On the second thought, the meaning is different in the second sentence because tiredness is not the reason for sitting down at the table here.
