Yesterday, I went to my friend's mother-in--law's 90th birthday party. Luckily, the weather was ideal. Mostly sunny and in the high 60's , I think. My friend has quite a nice house with a huge, sloping back yard. It was a very nice party. The guest of honor is having another party in July, near her actual birthday. Her friends will be at that one. I was included with the family yesterday.
As for a gift, I decided to get her a "then and now" book about Washington, DC. It shows photos from many years ago alongside photos of the same street, etc. from today.
