Your daughters are going to have wonderful memories years from now.
My biological sister and I were able to share one year together in ADPi-my freshman year and her senior year. It was SOOO much fun!
(And now her only daughter and my oldest daughter, while not ADPis, DID keep the "Alpha" and the three letters! Hers is an Alpha Chi Omega, and mine is an Alpha Xi Delta. I'm holding my breath for my youngest daughter to make it back to Alpha-and Delta-and Pi!!
