When you spent centuries keeping someone at a distance, and some of those keeping certain confusing feelings for that person at a distance, something like this could be confusing.

She blushed as she considered where her mind was wandering, to downright admiring Loki's form in battle and shook her head to rid herself of the thought. Instead Sif watched the trays get filled with the weaker sparkling drink fit for Midgardian celebration and considered for a moment she had never tried it before.
