Forecast - Showers this weekend

Well, after several weeks of my FH biting his tongue......I finally slipped in pre-cana tonight - telling him that someone had spilled the beans unknowingly, after the moderators asked if any showers happened last weekend. I knew a round about time frame for the shower.

I am definitely not one for surprises, so I am happy that I know know for sure.....I will try to act surprised though.

I am a tee shirt, and jeans person - do I dress as usual to acted surprised, or do I dress up a bit????? Your thoughts????
