17．If a friend does a big favor for us，it's a good idea to write them a thank-you note．But how many of us actually sit down to do this？
"People don't seem to walk around giving thanks to people quite often，" Amit Kumar from University of Texas said．Why are people hesitant （猶豫的） about sending thank-you notes？And how do people feel when they receive one？
Kumar and his team asked some students to write a thank-you note to another person via email．Then，they asked both the writer and the recipient （接受者） how sending or receiving these notes made them feel．
They found that the students didn't like to write the notes because they felt like they had to think too much about them．They worried about what to say and how to say it．The recipients，however，enjoyed the notes． "When you are a recipient，you focus on the warmth of the note，" Kumar says． "How heartfelt was it？How friendly and warm？"
The writers also thought it might be awkward （尷尬的） for the recipient to receive a thank-you note．But this was not the case． "They （recipients） feel quite happy，" Kumar says． "They don't really feel awkward at all．"
If people knew that writing a thank-you note could have such a big impact （影響） on others，they would do it more often，Kumar says．"Simple，small changes in our everyday lives can make a big difference in how we treat other people and how we feel，" he says．
