Your charge is proof positive!

This Static Charge Indicator uses two LEDs to indicate a positive or negative charge. A transistor present inside the device responds to changes in voltage that a charged object induces in the dome-shaped brass antenna. Most electroscopes require hundreds or thousands of volts to activate the moving foil leaves. The Static Charge Indicator is much more sensitive, responding to only a few tens of volts. Simply rubbing a plastic pen on your shirt several times is enough to trigger an unambiguous response from the LED charge polarity indicators. 9v battery included.

All atoms are naturally charged. This is because protons and electrons naturally carry a positive or negative charge. A stable atom usually has an equal number of protons and electrons, giving it a neutral charge. However, it is possible to transfer electrons from one atom to another. This occurs every day in nature, and is called static electricity. The effects of the atmosphere sliding over itself is sufficient to produce vast amounts of static electricity; lightning is simply the discharge of this energy.
