I just happened to bump into a woman doing just that on Tuesday and we started up a converstation about it, and breastfeeding and pumping in general. I realized that I could feel that odd sensation of my breasts letting down their milk - only, of course, they had no milk! Weird.
Then, today as I was driving home, I remembered the converstation and started thinking once again of breastfeeding and pumping and all that and darned if I didn't get the odd goosebumps-on-the-inside feeling AGAIN.
The human body is a very odd thing.
