Answer:
People create barriers that can prevent them from forging ties with others.
Explanation:
In Memoriam, A.H.H. and Alfred's "The Lady of Shalott," Lord Tennyson shows how people can create their own solitude by preventing others from approaching by creating barriers. That is, we can provoke our loneliness and be sad because we create psychological barriers that prevent us from creating ties with other people because we do not let them get close.
