Yeah to Hmmmm & Sharnita... but only if:
- this is the norm at these reunions
- all the life cycle events are being recognized
If it's specifically for Lord & Lady L's wedding and isn't normally done for births, retirements, graduations, and other weddings, etc., then I tend to agree that aside from the upcoming nuptials coming up in casual conversations, MIL should not be allowed any specific mention, toast, celebration, etc.
