Existentialism

Three questions:

1. Why, when everything seems to finally right itself, does something come out of the blue and make it all go to hell?

2.Why, when my cousin's ex-girlfriend who I have not seen in two years friends me on Facebook, do I immediately suspect that she is using Facebook to spy on him and anyone associated with him to get details of his upcoming wedding?

3. Why, just when I need it most, is there no chocolate in my apartment?

What a shitty day.
