Search Results: how to tell if someone is interested

Have you ever dealt with friends who are in silent competition with you? How did you notice? What is the best way to deal with friends like that?
What did these friends do? Did they, for example?

* Minimising your success.

* Go mute when you tell them about your success, accomplishment, or just good news?

* Try One-Upping you.

* Show "Copycat" Behaviour. (for example, you tell them about becoming good at playing basketball and suddenly they want to play basketball too when they were no interested before you said/showed you are getting good at it.)

* Forcing Competition: They act as a "rival friend" rather than a supportive peer.

A example, you're interested in dating a woman or guy, and suddenly your friend wants them too or the person to be interested in them more than you or wants their attention as well, claiming the person you want to date is just fun to be around etc).

* Did they maybe try to hijack or try to dismiss a compliment someone else gave you in their presence?

(For example a women complimnting you on your looks and your friend stepping in and tells the woman someing like ''Oh he is just tall, all women love tall guys'' .

Or another example a guy calling you beautifull in front of your friend and your friend telling them ''it's because she is wearing make up''.)
