THE DIFFERENCE BETWEEN THANK YOU & THANKS
If I say thank you and thanks don’t mean the same thing you may say I am petty. Though the two are means of expressing gratitude, they both do not convey the same message. One is personalised but the other is not. An average human being has ego. That doesn’t make him egotistic but a massaged ego can be the difference you are looking for when you seek quick results at the most critical moments, even under unusual circumstances.
