Has this happened to anyone else?

When I see my pledges through initiation in Sept. i'll be done with my office and will pretty much just be an active brother who comes to chapters and stuff because i'll be graduating soon. But since elections this last spring, it seems as if none of the new officers(a lot of them are younger guys in the chapter which is exciting) dont listen to anything i say in advice to help them to understand what doesn't work due to my past 4 years experience. They just totally blow me off and more or less tell me that i don't know what im talking about...almost as if im a NIB. I understand they need to learn some stuff on their own, but im also like, hey im the old guy here and i know whats up so you should really listen to what im saying....but they dont. Its like what i say isn't important or worth much. Its REALLY frustrating and i wanna just say,"Hey told ya so guys," but i don't wanna start a huge rift either. Have any of you had this happen and how do you deal with it. I wanna help, but i don't wanna keep trying if im going to be brushed aside all the time as well. Its really hard im finding out from going one of the top chapter guys for a long time to nothing in a short period of time. Guess one of the humbling lessons of pre-graduation to alum status. Thanks.
