Let's just say it's a good thing I don't own a gun

Me: I have a clog in my shower drain.
Mom: It's probably tree roots.  You're going to have to call someone.
Me: But I haven't even tried Draino yet.
Mom: DON'T USE DRAINO!
Me: ????
Mom: If you use Draino, a plumber won't even touch your plumbing...it's too caustic.
Me: ????
Mom: It's probably tree roots, you should call someone.
Me: *sigh* I have to go.
Mom: Ok, well let me know if you need a number for someone to get the tree roots out.
