Me alegra que hayas venido

[Tyrn]

Hi,

I'm glad you came.

Why subjunctive, if it's a solid fact?

[poli]

Phrases that express emotion usually take the subjunctive.

I agree with Poli.
Expressions like "me molesta que", "me gusta que", "me enoja que", "me fascina que", wich express how we feel about things, all take the subjunctive.
