brush from past

i have this habit of reconciling the day events before going to bed or whenever i get some down time ....like going n coming back from work...with my headphones on...so anyway, today on my way back from work i realized that i happened to meet 3 ppl randomly from my past...one waaaaaaaaaaaaaaay past and two other recent past, ppl who are not part of my life anymore ...but it was nice to meet them...
one of my old class fellow, whom i last acknowledged (saw/met/spoke to) when i was in class 5!! that means....around 13 years back!!! in 1993 ..oh god...i feel old!!! anyway i came across him on facebook....and we chatted a bit....was nice :)
other 2 colleagues ...one my boss najeeb and another colleague....so over all i would categorize this day as a brush from past....and its nice to have these moments in life ... in some strange way it makes us more human,,,,makes us realize that how every moment you live, every person u meet, every action u take has its repercussion...and one must always be at their best...u never know who from ur past decides to peek in and say hello:)
