A is for Amtrak
As in, a very pregnant lady shan't fly to Washington DC for the shower her law school buddies are hosting, instead she shall train there via Amtrak. Alternatively, A could also be for Alcohol, as in, the group I shall be Amtraking to, will be imbibing much alcohol. I could say that they are being driven to drink by the thought of me reproducing, but I suspect it is more because they are a lushy group.
Also, A is for Awesome, as in, "Dude, I think my socks are going to be Awesome!"
Well, I think so, despite my the look that my adorable model gave me which makes me think she would argue with my exclamation of awesomeness.
