Unfriendly Friend in SNS

The other day, I have a things to check and I asked a question to a friend who is in my friend-link list of SNS.

Then what he replied me makes me embarraced.

"Mr. Nightwish, which Nightwish?, I do not remember"

What a rude guy he is!

Hey, it was YOU to have applied friend-link to me, not other way around!!!

Yes, I just remember he applied friend-link to me without any correspondence beforehand.
When I received the application I had very strange feeling to him, like "Why he applied to me?".
However, I accepted his request because that SNS was relatively small and somehow business person oriented.

But this is my fault!

In order to carry on confortable life in SNS, do not accept friend-link from unknowns!
