Hey Pretty Stranger!

On my 14th Birthday I got a costly pen. It was personalised Rollerball pen! I never THOUGHT of using it,never ever. I kept it safely in my favourite box. Everyday after coming back from school,I used to check if it was okay. Days PASSED by and then I STARTED checking it weekly and after few months and I just completely forgot about its existence.

Almost after a year..One day I remembered my favorite asset. I opened the box and found it was there in the same condition.

Now I felt an urge to use it. For the very first time I uncovered that beautiful, expensive,delicate box. I tried doing Math with it (In hope of Math will be easy then

One..Two..Three..But the ink wasn't coming out! I got so frustrated,I tried doing every possible stuff. Alas! It wasn't working. I had to do Math with my regular pen (What's WORSE than that

The ink got dried because I haven't used it,not even for once.

Moral of the story :
