Suppose,You work in a factory that is situated 12kilometers from your house.Everyday, you cover the distance of 24kilometers,12 k.m up,12 back down.That is what we call travelling. Now, the boss of the factory became increasingly happy with the dedication you show at work.And in appreciation of your services,he has decided to send you to the UK on a two week all expenses paid trip.( How wonderful it sounds,by the way.)You go to the UK,definitely you are not going to remain yawning in your bed for the entire two weeks.Surely you'll move around the places,discover new cuisines, the beauty of the city and ofcourse, you would want to capture this moment in a selfie.Wouldn't you??? That is,my friend,what we call tourism. Hope it will be helpful.
