Primary School Friends - Never met more than 40 years ago

Today, I had a gathering of my primary school mates of whom, some i have never met more than 40 years ago. We met at Putrajaya Club house and had lunch there. we met for about 3 hours. Shared old photos and moments of fun we had together in our primary school - Islah English School in Kota Bharu, Kelantan. Altogether we manage to gather 11 of us, may be some other time in the future the number will increase. I hardly recognise most of them, grown old and most of them with grey and white color hair except for one of them who still look young.
