Whiskey Sours

Today was our celebration of Christmas with some of Fred's family since they were going to be away for the holidays.

We had planned to keep it a secret and so we were hoping nothing would come up to give it away.

Fred’s father always makes his "famous" whiskey sours. He made a full pitcher and offered to me. I declined (I almost always have one). He asked me at least 2-3 times more to have one and each time I had to decline. 
Midwife note: Don't drink alcohol when pregnant. This is usually a no-brainer. 

His brother-in-law also offered me cider, which I had to decline.

It was amusing because Fred’s family usually isn’t so pushy about drinking. I'm wondering if anyone suspects.
