Please and Thank You

These simple two words go along way but how it is said is more meaningful

Mostly we use these two words when you are asking someone to do something or when you are receiving something. However, in any situation – how these two words are said is equally important.

These two words can be used in terms of politeness, thoughtfulness, helpfulness or on the negative side as derogative and sarcastic. Which do you think would be perceived better: “Please get that into me today” Or “Could you please get that into me today”
At a young age we are taught to say please and thank you and it is ingrained into us to use it. Young children when asking for something, there parents would say “what is the magic word” and you would always reply… pleeeeeassssee.

However, did we actually mean that? Or did we simply use that word sarcastically to get what we wanted. Did we truly understand the meaning of this word? Or because it is what society expects us to say.
