I was invited to a wedding and when I get to the hotel, I realized there were two doors.
1st door it was Bride Relatives. 2nd door it was groom relatives.

So I decided to enter the groom's door and I found two door again.
1st Ladies. 2nd Men.

I entered men's Door and once again I found two doors.
1st people with gifts. 2nd people without gifts.

So I used to the 2nd door (people without gifts) and then I found myself outside the hotel.
