根据我的经验，消极（或为了某事沮丧）的人更容易听进同情的话语，而不是建议他/她应该这样做那样做。
From my experience, people who are negative (or upset for that matter) benefit more from an empathetic ear than suggestions/solutions on what he/she should do.
他建议街头甚至可以根据住户意愿种植果树并等待收获。
He suggested the streets could even be planted with fruit trees for householders to tend and harvest.
但我认为，他的建议完全建立在理论假设的基础上，而没有实证根据。
I think that he is basing his advice on purely theoretical assumptions, and that there is no empirical evidence for his assertion.
