Whatsapp is really a great app which keeps me busy in these days too.we can message, send videos in the click of a second using this app.my grandson stays abroad, I hardly get to meet them but through whatsapp my son sends his videos, his pics to me and I hardly feel any distance with them.this is indeed a great messenger.thanks to whatsapp which has narrowed the distance in todays busy world where we can freely message our loved ones.
