Bus Sleepers

Ever notice how people are willing to let go of their inhibitions when
they sleep on the bus. People don't notice that they look weird or do
things that they don't normally do. For example, a sleeping person
might allow her head to fall on your shoulder. In some cases, the
person might sleep-talk or snore. All this, in the company of the
hundreds of the people that go through the bus.

Why is it that people are so willing let their barriers down when they
are sleeping on the bus? And yet, they are embarassed when asked to do
other things. I think it is because they are asleep and so they don't
realise what they have done?

Well, you tell me .... zzzzz
