Every year MIL hosts. The last time we went was 2013. That’s because that was the year that MIL got her dog.
Since then SIL and BIL have also got a dog, MIL has got a second dog.
I am allergic and terrified as well. I can’t stand the smell of dogs either. We’ve offered for them to see us at our house (minus dogs) on Boxing Day- that’s not good enough. We offered to host last year - no, that’s not ‘the tradition’
Now dh is getting hassled with messages telling him to go - that my allergies and phobias shouldn’t be a barrier to his family Christmas!
