Well, we could write...""^(-)O-ddotS^+=O

Explanation:

...which gives a bent structure, where /_O-S-O=119^@.

Because there are 5 valence electrons around sulfur, rather than 6, the sulfur has a formal positive charge. The formally singly-bound oxygen is associated with 7 valence electrons, and thus bears A FORMAL negative charge, and of course you can draw the resonance isomer that equates the oxygen atoms.
