Angel - my experience in integrating into the community was from long ago, but hopefully the advice below will be helpful today:
Be patient and polite. Manners are a big deal - practice good ones!
Do hold babies, do smile at strangers and say hello.
Take your shoes off when you go into somebody's house.
Always offer guests a glass of water.
Walk dogs and play with cats at Saga Society - you will have fun, meet good people and make a positive contribution to many lives.
Assume that you know nothing and ask questions until you more or less understand. Realize that even though this is an English-speaking country, the meaning of words may vary greatly from your home country.
Listen more than talk. Think about things before you jump into them.
Don't tell everybody your business or brag. Many reasons why.
Don't flirt with somebody else's significant other (back to the good manners part ....) - take this one seriously.
Take your daily life at a slower pace - talk about the weather or whatever comes up when you are out and about.
I made friends and learned a lot about people and the community by working outside the home. I think that was the best thing I did to get into the swing of things.
If somebody rushes you to "help" or to be your new best friend - beware and use caution because they may be working a hustle. There are wonderful and genuinely helpful people here but also realize that the real-life folks of San Pedro have friends and jobs and a busy schedule already ...... they probably won't be the first people you get to know. Over time you will meet them and you will find your place amongst them (back to the patience and listening part noted earlier).
Expect some culture shock and relax with it, It's a very educational experience and can ultimately be pretty funny if you roll with it.
Don't expect this to be an all-upbeat experience. You will make mistakes about people and procedures and culture as part of your learning curve. The community is very forgiving of new-arrival mistakes so just relax and do your best. If you mess up, apologize and do better next time.
Do expect this to be a life-changing move and hopefully one you cherish. I jumped in with both feet 26 years ago and am still right here having a real and fulfilling life. I hope the same for you.
