What to write

It's hard to develop characters that will interact with each other.  For instances if I write about a old bus driver named jack who punches kids in the face when they bring sunflower seeds on his bus, well bad example he would be easy to incorporate in a script or screenplay because he is so dynamic...this is why i for me its easier to write comedy than drama.  In drama there are characters that are relatable because they are so real and thats what makes a drama dramatic.  But in comedy you can put anyone in a room and have them interact.  The key to writing is predicting what the audience will expect and do the opposite.  Sounds easy right? Try it sometime. :)
