Why exactly is H2O a nucleophile?

When you draw out the Lewis structure for water, you have two lone pairs on the water creating a bent shape. The lone pairs are regions of electron density. These lone pairs are attracted to positively charged atoms. They are "nucleous loving" and thus water is a nucleophile.

As a generalization, lone pairs are indicative of being a nucleophile.

Since there are lone pairs on oxygen, and since lone pairs are indicative of nucleophiles, H2O is a nucleophile.

But water can both lose an H or gain H. Why isn't water both a nucleophile and an electrophile?
