I usually work when they head out.

Last time I really tried to work there with the W.E.B kids there, Doreen's squirrel kept trying to eat the canisters of web formula I had out. [He cringes a little at the memory. He didn't have time to switch between Spider-Man to Peter, but needed the lab for something. It had been a... weird time.] I do not want to make her angry, making her squirrel kind of explode from the formula would lead to that pretty fast.
