Actually my personal belief is that all these days are created by card companies and other gift manufacturers to make money. I mean fathers day, mothers day, brother, sister, boss and god knows what more. You don't need any special day to celebrate your relations. You can celebrate it everyday by being true to your relatives, friends. Give them respect and earn it as well.
On DFI everyday is a friendship day as we meet new friends and get to know them. We don't see each other but develop respect and love for each other. That matters.
