My MIL is absolutely stupid. Hilariously stupid. 

SS was at home, spending half of holidays with us. BM agrees to let SS spend the other half at MIL and allowed her to come and pick him up at our house. 

MIL asked DH if it was possible to come on early afternoon in order to spend some times with BS. She didn't see him since many months, so DH agreed.

DH explained that her request will have many impacts on our journey organisation (DH taking his afternoon, BS coming early from kindergarden, Me working from home on the afternoon and SS ending early his activity center) and that she must be on time. She was OK. 
 

Today, the great day. DH, BS, SS and I were waiting for her, but she was in late. DH called her to ask where she was, and surprise.... she still was at her home ! Finally she arrived with two hours delay. It was snap time for BS, she only saw him few minutes. I say "saw" because she just spent these minutes playing with SS (who was super happy to be the unique center of attention). 

Then, she stayed 10 extra minutes explaining to us why she was in late : yesterday she just found a baby cow on the road, and she had to take care of him and bring him to her home. The baby cow didn't survive through the night and she spent the day finding out solution to bury him. 
 

This was so hilarious and comic i was asking myself if i wasn't dreaming.

Course she left with SS super happy to spend privilegied times with him. 

I might write a book
