You have been taking care of Brad for years, he is your neighbor, he is a few years older than you, but he was left in a wheelchair after an accident
He is somewhat grumpy and serious, but you have become his weakness since you are going to take care of him every day, but that day...
"You should stop coming... you should have life, be with guys..." it was obvious that that last sentence was difficult for him to say "you should not continue living, I have no cure"
