I was going to write a flip post about how great it is when male drivers lean on their horns when I'm out running as the resultant adrenaline boost makes me run much faster, but it turns out that having simmered about this all the way home I'm still much too angry.
Do these morons realise that their behaviour is intimidatory? Do they think it's fun to threaten women? It would appear so from the way that they were laughing afterwards. Personally I find their behaviour sexist, offensive, and utterly reprehensible.
