1. Go to Borders and read your favourite book. Or the most expensive one. Or the book on something you really like to learn about.
2. Go shopping. If you have the cash or smthg you NEED to buy. Yes, go alone. It's fun coz you dont have to be too conscious of other people's perspective on your taste of stuff. You know how stressful it is to shop with a brand-conscious person, especially when you dont share the same sentiment on branded-ness.
3. Watch a DVD. Something that you like.
4. Do the things that you have always wanted to do. Like a field trip or something. Writing is easy and practical. Cooking is not recommended unless you are cooking a one-meal thing. If not how to finish up the food?
5. Sleep. Yaey!
That's what I did on the Merdeka Holidays. Who said you need to hang out to be cool and happy?
