Context: This guy has some seriously bad BO . And I ' m not even talking about just raunchy , have n't showered lately BO , but that rank , almost vinegary sick - stink . I ' ve mentioned it before , just kinda bugging him that whatever deodorant he used was n't working , but since then I ' ve pretty much left him alone because one of the operators jokes with him about it almost daily , trying to prompt him to use more deodorant , and that kind of worked , but not enough . Today was n't even that hot !

Question: Why do you think he simply does not fix his body odor problem ?
Options:
0. he does not care what others think
1. He is unaware of how bad it is and likely does n't realize that he smells
2. he does not care that the smell is offensive to other people
3. his girlfriend likes the way he smells and he does not want to change it because she likes it
Answer: 1
