Dear Hamilton,

　　We are fortunate that in such a large, high-pressure office we all get along so well. You are one of the people who keep the social temperature at such a comfortable setting. I don't know anyone in the office who is better liked than you.

　　You can perhaps help with this. The collection of contributions towards gifts for employees' personal-life events is becoming a little troubling. Certainly, the group sending of a gift is reasonable now and then. In the past month, however, there have been collections for two baby shower gifts, one wedding shower gift, two wedding gifts, one funeral (葬礼) remembrance, four birthday gifts, and three graduation gifts.

　　It's not only the collected-from who are growing uncomfortable (and poor), but the collected-for feel uneasy receiving gifts from people who don't know them outside the office, who wouldn't even recognize their graduating children, their marrying daughters and sons, or their dead relatives.

　　This is basically a kind gesture (and one that people think well of you for), but the practice seems to have become too wide-ranging and feels improper in today's office setting.

　　Thank you for understanding.

　　A new study has found that social media could be affecting the sleep of young adults.

The study is a project of researchers at the University of Pittsburgh's School of Medicine. They found that young people who often use social media are more likely to suffer from sleep disorders than those who use social media less. The researchers say doctors should ask young adults about their use of social media when treating sleep issues.

"This is one of the first pieces of evidence that social media use really can influence your sleep." said Jessica C Levenson. She was the lead author of a report on the study.

The researchers set out to examine the connection between social media use and sleep among young adults.. Levenson noted that these young adults are possibly the first "generation to grow up with social media. "

The researchers wanted to find out how often young people used social media sites like Face book, Twitter, Credit and Tumbler. For the study, they gave questionnaires to nearly 1,800 adults, aged 19 to 32. On average, members of the study group used social media sites one hour a day. They
