Nothing much to do is true.. but if two person shares common
interests, maybe this activities won't be that hard to think
of...
can sing K, play pool, workout, watch movies, walk aimlessly,
Sea watching.. etc..
can even go to places of worship, tourist attractions, take
photos, nature walks.
come up with a story plot and sketch them together. talk to each
other on politics, problems or even personal stuff..
actually it's not the number of things available to choose to
do, but the company and money you willing to spend to do.
