Q: i’m being harassed by girls. they took a picture in front of my house, and posted it. they drive by me and laugh

A: Taking a photograph of the front of your home and posting it, then driving by you laughing isn't harassment.

In my jurisdiction (i.e. The State of Texas), the crime of "harassment" is defined as follows --

(a) A person commits an offense if, with intent to harass, annoy, alarm, abuse, torment, or embarrass another, the person:

(1) initiates communication and in the course of the communication makes a comment, request, suggestion, or proposal that is obscene;

(2) threatens, in a manner reasonably likely to alarm the person receiving the threat, to inflict bodily injury on the person or to commit a felony against the person, a member of the person's family or household, or the person's property;

(3) conveys, in a manner reasonably likely to alarm the person receiving the report, a false report, which is known by the conveyor to be false, that another person has suffered death or serious bodily injury;

(4) causes the telephone of another to ring repeatedly or makes repeated telephone communications anonymously or in a manner reasonably likely to harass, annoy, alarm, abuse, torment, embarrass, or offend another;

(5) makes a telephone call and intentionally fails to hang up or disengage the connection;

(6) knowingly permits a telephone under the person's control to be used by another to commit an offense under this section;  or

(7) sends repeated electronic communications in a manner reasonably likely to harass, annoy, alarm, abuse, torment, embarrass, or offend another.
