Talk to them! Seriously! Or just kinda make little comments like "left out...again.." with like, a joking upfront but a serious undertone and they will get da hint.
Talk to them about it, individually. Tell them that they shouldn'tforget about you and remind them that you ARE the reason that they are friends.
I think that it might help your friendship if you A)talk about the stuff that they are into or B)hang out with some other friends.
I had the same problem last year. I confronted both of them, and once I did, they started including me more. All three of us are now great friends!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
