Particular Point Space is Non-Meager/Proof 2

Theorem
Let $T = \left({S, \tau_p}\right)$ be a particular point space.

Then $T$ is non-meager.

Proof
By definition of particular point space, any subset of $S$ which contains $p$ is open in $T$.

So $\left\{{p}\right\}$ itself is open in $T$.

That is, $p$ is an open point.

The result follows from Space with Open Point is Non-Meager.
