['I feel so thankful for my mother-in-law. She recently sent us a great feast of food out of the blue.', 'Wow, how nice. Is she always doing nice things?', 'She does actually, and very randomly! Which I love and find to be kind of unique.']
Wow, you are lucky to have someone like that in your life. That's rare.
My mother in law recently sent a great feast by way of my wife, and I am very thankful for that.
