Based on the Merriam-Webster the word Interludes (noun) means a usually short simple play or dramatic entertainment. On page #279 in “Sweat”, it state that, ” Delia and Sykes fought all the time now with no peaceful interludes” based on this quote we can said that in their marriage there were always fights. Delia was used to live in this environment of drama and this is why we can say that she got to her limit with him and let him die, she was tired of his abusive character towards her.
