when i first read this, the first thing that came to mind was our going away party when we left palestine. it rocked my socks off. but, it was actually in 2009 (we've been gone a whole lot longer than i thought....) so it can't count.
so instead, i'm stealing mel's answer - hendy's wedding. it was so fun. we got to see friends from college that we hadn't seen since we left for palestine. we were only up in siloam for a weekend, but we hung out with people every night. we got to share stories, catch up on life, rekindle friendships, laugh at memories, and just hang out like old friends.
the wedding was beautiful and the the reception was great. it was at this country house with a huge field that hiba absolutely loved running in. the wedding was also fun for us because we got to really introduce hiba to a lot of our friends. some had met her before, when she was a baby, but since she got to come to the reception with us, people go to see the wonderfulness of her in action.
so the weekend was great. we always have a great time with old friends, and this was no exception.
