Sif looked up to find one of the workmen there and she smiled a little tearfully. "I'm sorry," she demured with a shake of her head. "I- he just reminded me of someone I used to know. I'll get you all some coffees." She quickly went back into her own shop and out the back in the little kitchenette she sat at the table and cried.
Then, when she felt she was done with that (at least for now. Sif was always so easy to move to tears) she made enough coffees for them except for not-Thor. No need to disturb him more. No need to disturb herself more.
When she returned to the next door building it was with a bright smile, even if her eyes shone a little more than they'd done before. "Coffees," she announced, but didn't look for the man who made her body tense. She barely raised her eyes for fear of seeing him now.
