“It’s been a while since I’ve been on FB & I thought I’d drop by to let you all in on some exciting news. Honor is going to be a Big Sister! Cash and I are thrilled and wanted to share the news directly with you so you didn’t hear about it somewhere else. I appreciated all of the love and support you all gave me during my first pregnancy and will definitely appreciate it again this time around. Have a great day! Jess.”
Now you can’t say all that on Twitter, can you?
Although, when someone says they want to “share the news directly” with you, it’s usually not through Facebook.
