How Hard Is It to NOT Knock Over Plants, Really?

Keeping succulents healthy on Moore Street is difficult because the house does not get a lot of light. A while back I figured out I could get succulents a pretty good amount of light by placing them in the downstairs bathroom window in the morning...

...and then moving them to the kitchen window in the afternoon. Note: the picture below was taken in the morning and is for demonstration purposes only.

For some reason, nobody but me can grasp this and I am constantly moving the plants back and forth. What's even more troubling is that Alice, Eleanor, and their mother, routinely knock over the plants. I was in the house this morning and I noticed that both of these plants had been knocked over very recently. 

The plant on the left is new. Eleanor bought it for me at the street fair last Saturday. The girls' mother knocked it over two days ago. I had this great exchange with Eleanor via text:

E: "The reason there is dirt [in the bathroom] is Alice knocked over Gladys 2 And the other one, the new one was knocked over by mom but she won't admit it"

Me to Me: "Christ on a bike! How fucking hard is it to NOT knock over a plant!?!?"

Me to E: "Don't talk like that about your mom."

E: "Okay sorry"

Me: "I think 'Bon Jovi' would be a great name for a cat."

E: "wow"
