I love to sit outside and eat, watching people walk by. Everywhere in in Spain and France they will cram as many teeny tiny tables together as they can possibly fit onto a small sidewalk space, right up to the street edge, with cars and motorbikes zooming past, fumes everywhere, the tables as so close you sometimes have to crawl over other people to get there.
The funny thing is, these are considered the most desirable spots!
Not here though. At least no where that I have been in the United States. We are not generally a very social society. Yes, we do all have friends and we socialize with them, but we are very much into our private spaces, our own, plush surroundings, where no one can come close or bother us.
On the other hand, in Europe, you can sit and have a drink, water if you like, order some food if you want and continue sitting, and watching. The people watching is amazing.
I like to sit outside and look at everyone. I can tell who feels confident about themselves, and who is dressed up but feels uneasy because their clothes just don't fit right.
If you are comfortable in your own skin, you should feel right at home in just about anything. If you are not, it is time to look at your diet and your exercise (or lack of).
Take the stairs not the elevator; park in the outer most space at the grocery store (keeps those pesky carts from dinging your car too); go for a walk around the block after dinner instead of watching TV; walk your dog; walk your partner; walk your neighbor! It's a great way to catch up on things.
And food, well that is a subject I can go on about for ages. Let me just say here: avoid packaged foods. Don't eat at fast food restaurants. Limit any restaurant or pre-made foods. Be beware of "low fat" or "fat free", they often have just as many calories as the full fat versions. Learn to love vegetables. Drink more water than you can imagine. Limit alcohol to special occasions.
Feel good about yourself.
