In response to 'What would Buddha actually do in case, He was in my shoes? In case Buddha was in my shoes, He would look like a common person,totally "normal".One couldn't realize Him from the outside as being an Awakened One'.
One thing that springs to mind here is dependent origination. Beings or indeed things are not 'just like this', a particular way, fixed and objective, as it were. How beings appear to you would be dependent on many, many factors, and thus a Buddha (just like anyone else) would appear to each person in a unique way, dependent on all the operating conditions.
In a sense, the way that they would appear to you would be dependent on your own realisation. Thus you would see the Buddha in either his Nirmanakaya, Sambhogakaya or Dharmakaya aspects.
