I just wanted to pipe in here for a minute with a few minor details. Lulu forgot to say the friends we're visiting are scheduled to have their first child in a about a month. On top of that they've been spending all their free time doing fairly major construction converting an out building into a guest house. This has included the 7 month pregnant wife burying utility lines. That's right. here's a math formula to illustrate this scenario
8 month pregnent lady + major construction = Exhausted lady who isn't getting much sleep
These ain't no sissy folks, but I don't know it they're ready for the little sleep they've been getting to be disrupted but our suddenly slightly more fussy baby boy.
Exhausted lady who isn't getting much sleep + fussy baby screaming in your ear = X
Solve for X
I know they're looking forward to seeing us, and I can't wait to get my farmhand on, but I think Lulu's right and we've possibly made another series of unwise decisions here.
