This is my first managerial position and I’m very tense.
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means tighten, so the verb vocab version is to tighten.
Right now, you're trying to tighten the wool on this sheep (し). You grab the sheep in your arms and you tighten and tighten and tighten your grasp until...!
The sheep tightens into a tiny little ball. Cute!
