Fate or freaky coincident?

Mr Kutu and I share many common stuffs.  Apart from similiar habits, similiar BAD habits and common interest, there are some other things which I feel, are hints to tell us that we are made for each other.

1. We both have three 4s in our IC numbers.  And they all fall in the same place.

Mr Kutu-S84×4xx4H

Mine-S84×4xx4E

2. I have a friend who share the same birthday as Mr Kutu and my friend’s gf who shares the same birthday as me.  And they have been together for quite long also.  (I know this only shows that our character match.)
3. And recently, I found out that the duplicated key for his padlock at his house is able to open my house lock.  And vice versa.  You can tell me it’s coincidence, but can yours open your partner/spouse house lock? 

So, I choose to think that this is fate and not just a simple coincidence.
