WHAT IS THE FIRST THING YOU NOTICE ABOUT SOMEONE YOU MEET FOR THE FIRST TIME? PART 2
There are well-groomed hands, which may mean that you're doing a kind of job which doesn't involve hands or that you're just someone who loves taking care of yourself.
If your fingernails are bitten or chewed off, you may be an anxious or nervous person. Or if you have nail polish, you're probably someone who loves fashion.
To sum it all up, hands can give you many bits of information about the person standing in front of you. Of course, it's not an "exact science", so most of the time you can only guess until you actually get to know that person.
Anyway, observing hands can be a fun way to determine whether you might be a good investigator!
I split the answer in half. If you're willing to correct me, please look for part 1 too. Thank you!
