 For example, a person might think that someone is being rude if they will not look them in the eyes - or doesn't understand cliches like "it's a piece of cake", when in fact there may be a reason for this.Depending upon the individual's level of functioning, a person who hears "it's a piece of cake" may take that literally and not understand that what is really meant is "it will be easy".For someone on the autism spectrum, being in an autism friendly environment means they will have a manageable degree of sensory stimuli, which will make them calmer, better able to process the sensory stimulation they receive, and better able to relate to others.
