So I used to be really good friends with this girl in high school, but we drifted apart towards the end. I became really good friends with her younger brother, though. Every once in a while he will wander into my job to see how I am, and we'll talk for 10 or 15 minutes. Turns out my old buddy is heavily pregnant, and about to have her kid (this week!). In a way I'm happy for her, but in another I'm not. Her brother thinks she intentionally became pregnant to trap her boyfriend into a relationship he had wanted to end.
She was a really sweet girl when I knew her. I haven't talked to her in about 2 years (since we graduated), but I sort of want to send her something. What would be appropriate, if anything?
