First impressions.

Think about the moment when you enter a new building, see a new place or check into a hotel you've never visted before. This first impression when the place feels strange, ackward, new. Like a piece of clothing that is not that comfortable or simply unfamilliar.

I like the comparison between this first ackward moment and a bit later - the third, fourth day in some place when you've already got used to your surroundings and they are starting to feel familiar, known, yours. Some places than start feeling like at home, others feel out of place and it takes huge amount of time to change this. 

But even with places that feel like home you feel that little sadness when thinking about the first time you've experienced this place - the oddness, freshness, outworldly feeling it gave you. 

That's why it's so good to travel to new places you've never been before...
