We went to the gym 4 times last week. We only saw you once. Please do not say "I only saw you once this week, I thought you guys were giving up already?" and then wink at us. You see, that would be like me saying "I only saw you once this week. I though you got fired. Or killed." And then not winking.
Winking doesn't take the aggressive out of passive-aggressive. Neither does writing about it on a blog that you don't read.
