How do you tell if an old friend likes you?

you can usually tell if an old friend likes you by the way they act around you.they usually start to prefer your company and want to hang out and go out with you more.sometimes you can also tell by their body language.they might give you more hugs than they did before,or sometimes they try to tell you that they like you by giving you little hints here and there.pay close attention to what they say,because they probably don't want to tell you that they like you straight forward.they want you to find out on your own.
