Think about what your first impression might be if you saw a grown man who stuck wildly colored feathers all over his body and danced up the middle of the main street of a large city. You might think that he was crazy, suffering with a psychological disorder.

Now, think about media footage you have seen of Mardi Gras, the carnival in Rio de Janeiro, or the Philadelphia Mummers' Parade. (If you haven't seen this footage, feel free to google it.) With this in mind, the above scenario doesn't seem as "crazy" anymore. Many cultures reserve special days for public celebrations in which violations of the accepted norms of behavior are temporarily tolerated.

Help me talk about 3 behaviors you have witnessed that might be considered abnormal if the context was not taken into consideration.
