3rd wheel

Can anyone think back to elementary when if you were a kid like me you had few friends but you always had that one friend that was popular . And when you were in a group you just felt like the odd one out. Well if you weren't let me tell you how awkward it can be. Especially if you were shy like me. There is nothing worst than feeling like a 3rd wheel.

Okay what about when your best friend gets a boyfriend and you're single. But your best friend wants to hang out with you and him so she doesn't leave you out. But while they are cuddling, holding hands and laughing at the cute things they're doing you are sitting across for them feeling like a loser, and imagining that the whole restaurant is watching you .

Does that case of loser ever go away?
