Thank you for the opportunity to help you with your question!
a bad attitude is the feeling of not considering other peoples feelings, more of selfishness. seeing that they are always wrong and refusing to own up even though you are the one who has faulted.
some behaviors like being bossy and unwilling to act like a person who wants to change a situation from 0bad to good. people who do not care about anything and generally, the kind of people that bring the problem instead of helping solve the problem.
Please let me know if you need any clarification. I'm always happy to answer your questions.
