Coincidences often occur in everyone's lives... Seeing familiar faces while walking on the streets, realising that a certain someone used to be ur ex-classmate in primary school etc... All of us should have experienced that feeling before... one of deja vu, one of great surprise, one of rekindled interest... and coincidences often invoke pleasant feelings in us... if anything, we seldom remember those of unhappiness...
Some things are just meant to happen while some others are not meant to... And some things might somehow change with the occurrence of coincidences when we least expect them to... And that's the time we can truly declare that miracles do happen in this world... =)
