All my friends are 21 and Im not! Will the novelty wear off for them?

Me and my buds used to always hang out together, pretty much every weekend. The problem is they are all 21 now and I just turned 20. All they want to do now is go to the bar, which I obviously can't do yet. Will the novelty of being 21 wear off after awhile, or do I have to find new friends for the next year?
