How to construct this metric space Please give an example of metric space that there are two open balls $B(x,\rho_1) \subset B(y,\rho_2)$ for $\rho_1>\rho_2$

If your $\subset$ allows the possibility of equality (i.e. $\subset$ means $\subseteq$), then letting $d$ be the discrete metric on any non-empty set $X$, we have that $B(x,3)=B(y,2)=X$ for any $x,y\in X$.
