This week's theme: Mark

• I have an old notebook where I mark my family and friend's birthdays but haven't added any new entries for a long time.
  

• I mark my son's things with his name like books, school things, etc.
  

• I know a couple of guys with the name Mark.

• I mark the days left before Christmas inside my head.
