Then who called me ?

Me and my family lived at a bungalow with only 3 bungalows around. It was a peaceful and beautiful place.
We had good neighbours .
And my children played with Verma ji the old man and his wife who has recently shifted here like their own grandparents.
We were very very very happy.
One day I had to work late in the office so started to come home at late night.. around 12 o clock ….
I was thirsty and hungry so I went into the nearby restaurant to have my dinner.
But when I was eating my dinner I got a call from an unknown number …
I recieved…
There speaks a young girl in a hurry…
” Hello ..
Are you Abhishek Sharma ??” She asked me ..
” Yes I am Abhishek but who are you ? ” I answered
” I am Anamika Verma , Verma Ji’s grand daughter.. But we don’t have time to talk about all this !! You need to rush to home fast because your wife Tarvi….” She said…
I was scared when she took my wife’s name !!
“What?? What happened to Tarvi ?? ” I asked hurriedly
” Tarvi slipped from the wet floor and had got a serious head injury …..
She is lying fainted on the floor…
She could even die if not taken to the hospital in time!!!!” She said
After hearing all this I was so much worried that I rushed towards home even without asking how do she know all this because our neighbours Verma ji and his wife lived alone in their house..
I rushed home …
And yes it was all true…
My children were sleeping and Tarvi was lying on the floor fainted and bleeding due to the head injury.
I called the ambulance. And asked my nieghbours to take care of my children.
And then took Tarvi to the hospital…
After 1 day when Tarvi was out of danger I came back to home .
I saw Verma ji and his wife were playing with my children , my neighbour Arpita bhabhi was cooking food for my children and neighbour Prashant was cleaning the house …
I was just touched by the kindness of our neighbours.
I went home and thanked all my nieghbours…
And then I gave a special thanks to Verma ji and his wife …
Mrs. Verma asked me ” why are you giving a special thanks to us child?”
” What did we do ? ” Verma ji added
” Ya actually not you but your grand daughter Anamika , she was the one who told me about all this” I told them
But the Verma couple looked surprised
“Grand daughter??” Verma ji asked in doubt
” Child but we don’t have any grand daughter … We just have a 9 year old grandson Raghav” mrs. Verma said
I was scared after hearing this and said
” Then , then who called me?”
….
Nobody knows that who called me and saved my wife’s life that day and the phone number …
My call log don’t show that call it just says my last call was a outgoing call at 8: 30 pm to my boss….
