Why not buy a Diary/planner so that next time you have 18 days off you can forward plan and then maybe book a holiday somewhere nice instead of sat at your computer with nothing to do asking for suggestions.
Are you a police officer? If I had 18 days off I'm spend it on myself i.e. exercise, hair, skin,nails etc make sure I felt really good about myself and then chill out is it sunny where you are?
Hiya! I am not in work today nor will I be for the rest of the week! I am a student! I plan to be a student for the rest of my life coz it is so much fun! LOL!
