Sense of smell returning?

[00goddess]

Our dishwasher pops open a few minutes before the end of the dry cycle, to release steam and finish drying. Last night we were sitting on the sofa and I smelled something like detergent. I said to B "I smell something." His response was "It's not me," and I said "No, it smells like detergent." He said "The dishwasher just popped open."

I've never smelled the dishwasher opening before. Maybe my sense of smell is returning? I had a very sensitive sense of smell before my sinus surgery.
