I'm a pretty open person. You ask and I'll usually feel comfortable answering. I used to be a lot more open than I am now. I'm not sure if that's a good thing. I've noticed that people are so closed off when they first meet someone. Not that I can blame them. It's hard to be real and open, especially when there's the risk that you being you won't be accepted. People aren't quite sure how to respond to someone who is genuine. It's abnormal and somewhat intimidating.
Trust is a big issue in today's society I think. People trusting people is starting to decline rapidly. There was a time when you could let your kids outside to play and not think anything of it. You knew they were safe and that no harm would come to them. Now, in today's world, you barely let them out of your sight. Why? Because you don't trust the people around you. People have abused that trust.
When trust is damaged, it's hard to get it back. It takes time and constant proof that you're a trust worthy person. Even then, nothing is guaranteed.
I used to be a very trusting person. But when a person gets burned enough, their faith in people starts to fade. At least for me it has. I'm still trusting, just not as much. I step with more caution and open up less. I look carefully behind every door and step over every pebble.
I'm not convinced this is good though. I don't think it's altogether wrong, but unless you trust people, you could miss out on a lot. Even when that means being hurt. Without pain and without hardships a person doesn't grow. I'm not suggesting to trust any and all, but maybe step out a little. Open that door a little more widely.
Deciding whether or not to trust a person is like deciding whether or not to climb a tree, because you might get a wonderful view from the highest branch, or you might simply get covered in sap, and for this reason many people choose to spend their time alone and indoors, where it is harder to get a splinter.
