Stick / glue object to another

Do you know the way to permanently glue one object to another?

I would like to have my object connected with other object and placed always at the very left side of it. So when I move the second object then the first object moves with it (this can be done by grouping but next thing not), and when I resize the second object (for example shrink from left to right) then the first object stays at the new left edge of the resized one.

Can this be done?
