Mistake

I have to apologize that I had a mistake.
I wrote that I saw cherry blossoms in my neighbor. But it was wrong.

It wasn't cherry blossoms but plum blossoms.
When I talked about the blossoms to my friend,  she immediately denied. 
So I searched to prove it.
Finally I found that the blossoms were plum tree.
Indeed...it's not enough warm for cherry blossoms yet.
I show you how to distinguish the difference between the two blossoms.
