Quite honestly, weddings are so loud I find it difficult to carry on a conversation anyway. So I don’t mind sitting there in silence. I think the OP is making too much of this at a wedding. I could see maybe in other settings it’s more fo a concern. Having said all that, I tend not to stay past chupah anyway.
One final word: Unsocial, you are assuming that no one else there has a similar issue? Maybe they are all waiting for someone to reach out first.
