Forget about introverted. I have social anxiety, and don't have much in common with my ILs.
Thankfully they talk and I listen and nod and smile and play the part of the submissive Asian DIL.
I've had to suffer through So Much Worse. This is nothing in terms of tedium or awkwardness or plain social panic. I've had to give speeches in front of hundreds of people, OP - me, the person with social anxiety!
If I can do it, so can you.
