阅读理解

     I'm often told how I have a dream job, that I work for a great company, getting to deal with the

leaders in social media every day, and especially that I get to work from my home.

     Usually the people who tell me that working from home is wonderful have never worked from

home.  They spend most of their career working from an office and hate it.

     In fact, I love being able to work from home and make my own hours. I truly appreciate being

able to drop what I'm doing to attend kids or go shopping, but there's a side to it we don't often talk

about, the hard side. No one wants to believe people like me, working from home, have anything to

complain about. Really, I'm not going to complain, but I do want to share a few things about

telecommuting(远程办公)that few home -based people want to tell you, because working from home

doesn't look so wonderful.

     One of the reasons I love my job is the flexibility. I know that I can volunteer for school projects,

meet friends for lunch and work out for an hour as long as I get my work done. But did you know

telecommuters have to make up the time if they wish to pepper their days with fun distractions?So

while my husband and kids are watching a movie, I'm working until midnight. Besides, when you

work from home, you're held to your phone and Skype(网络电话)in case someone wants to talk to

you during business hours. So it's not so easy to be flexible!
