Maria, it's awesome news about the job! Sounds WONDERFUL!
The staying with the inlaws for 3 months? Heh! Not so much! I've done that, and even tho I loved my MIL and worshipped the ground she walked on, two women in the same house that are both used to being "the woman of the house" doesn't usually work well. I wish you all of the best in that department, and hope the "time eaters" work well for you!!
