Okay...seriously...get your holiday cards out. You're running out of time. Even if you have no stake in the holidays, this is a prime marketing opportunity to thank your clients for their business over the past year.
In the passage , please tell me w­hat the coloured -pink words mean?, thank you very much, and it­ would be good if you could give a remark wh­ether it is true or false for my question
If you're sending holiday greeting cards to your clients by mail, do the work of signing them, putting them in envelopes, putting the correct address on the envelopes, adding proper postage, and getting them to the post office.

Even though you don't personally stand to receive some immediate return from your effort (your product and your clients are not holiday-related)

I'm sorry. I don't understand. True or false for what question??
