I was cutting my backgrounds for my 10 gallons today and I measure it out on the front blocking their view from everything. I got glared at! Made me laugh. So I did it again. XD
I do a lot of what they suggest already. Things get changed outside constantly. I like holding stuff up for them to look at too. Especially for Apollo because he's in the hallway and doesn't get to see as much of what is going on.
