mysterious person

2 days ago, i received this email:

BUT the problem is:
1. I was at home but i did not on my computer until late at night.
2. I have no money lah... how to pay?
3. I do not intend to buy Harry Potter, yet.. so how can i order this??

So i emailed them an ask if there was any problem. But they sent me an email with my correct particulars. If you type the wrong email add, you cannot probably get all the details wrong right?

And so i emailed them and ask if payment has been made and they said yes. Apparently someone purposely sent this to me.

BUT WHO?? i do not know of anybody who will send things to me for no particular reason. Some ppl suggested my bf then i said that he will not do these kind of things. Then a friend said that i oso said the same thing during v-day that he will not give me flowers but i got a bouquet for v-day. That time i was so happy. SO maybe it could be him... but wat spurred him to do this?

Meanwhile, can anyone tell me if they are the mysterious person? Thanks!
