Lately I went out with my friends and I noticed that some of my male friends acted completely strange maybe not strange but more openly towards their female coworkers.more here to say about their body language they were touching rather hitting their arm with hand like oh I want to tell you something and than bum on the arm but lately he was clapping on her lap like kind off girlish way not gay lately I told her that I think he is attracted to her she started laughing but I have known him longer and I can see that there is something.so when guys really like girls as friends and where actually look for sings of attraction.because if she is right that means my judgment is wrong so I don't want to put myself in the future with embarrassment that I read somebodies gestures or acting towards me completely wrong.so what are sing of attraction what are just friendly gestures where is that difference

Some guys are flirty.

Just as some girls are. Its hard to read any signs.

If they do spend a lot of time together. And you always see him looking right in her eyes.

For a long time. That's a good sign that there is something.
