hate behaviour that targets people because of their perceived differences.
This is by no means an exhaustive list. The important factors in determining ‘what is’ and ‘what is not’ anti-social behaviour are the level of seriousness and frequency of the behaviour. There is a balance between tolerating behaviour that we personally may not agree with and ensuring that we tackle behaviour that is anti-social.
If the problem is not too serious, try talking to the person. They may not realise they are causing a nuisance. Be calm and friendly, explain what the problem is and how it affects you. Listen to the other person and try to reach an agreement. If the discussion is getting unreasonable, leave and report the anti-social behaviour.
