I am an extreme introvert and, sometimes, I really want to just hibernate. I let myself take it easy but, unless I am ill, I always go out at least once to explore and just be present. Here are some simple outings that you can do anywhere, even when you don’t feel up to much.
A walk in the park.
This is a great way to explore a city and see what local people do for recreation.
Pick up snacks at a grocery store.
Explore the local grocery store to get a good idea of what people like to eat, and to rub shoulders with real people.
Stop at a street vendor or farmer’s market for fruit.
See what’s different between home and your travel destination.
Or just wander about…
Poke your nose against windows, try to decipher what signs mean…
I sometimes explore an area by just walking around and trying to figure out which Chinese characters (or what-ever the language is where you are) I recognize on signs.
When we went walking in France with my son (in the days before digital cameras-he was 12), after we settled for the day I would send him out to scout restaurants as language practice (I stayed within sight, but let him do it on his own). Since he decided where we ate he was quite amenable to trying new things. Turned out he really likes duck.
…or just have an ice cream.
I have had some great experiences, and many, many tiny cups of tea, as a result of just going out, without a detailed agenda.
