6. Play tourists
It is impossible to describe how interesting and fun it may be to play tourists! Grab your camera and set off in your trip around the city discovering new fantastic places. Imagine that you see those surroundings for the first time and look at the city with new eyes. Ask strangers to take pictures of you two together. It will be even more amusing if you both speak foreign languages. Trick everybody and pretend to be different people, it will draw you two together even more.
