I'm lazy, that's why I didn't ............
Does it sounds familiar to you? That's a very useful sentence. It suits any kind of situation and if you add some tired expression, nobody will blame you (if they are in good mood).
I've been quite lazy, all the while. Lazy to go for manicure, lazy to trim my hair, lazy to do research for my new laptop.... I think I'm lazy to spend money. *fireworks!! boom boom boom!!* unusual but true for the past 3 weeks.
Today I don't feel like doing anything. Nothing at all. Yes, I don't feel like typing now. LAZY PIG is going off. bye!
