Sure. And I'll assume that you mean the negative synonyms, and not the following:
acknowledging, active, alive, answering, awake, aware, compassionate, conscious, forthcoming, impressionable, influenceable, kindhearted, open, passionate, perceptive, persuadable, reactive, receptive, replying, respondent, sensible, sensile, sensitive, sentient, sharp, softhearted, susceptible, susceptive, sympathetic, tender, warm, warmhearted.
Sometimes 'reactive' can be great, especially when burglars are in your house. |
