Advertisement This issue has always bothered me but I'm not sure whether it's important enough to freak out over. So many times, people will walk in my room where I keep my Ts, and if it's nighttime, they'll turn on my lights and make the whole room bright. I'm worried that that could disturb and confuse the Ts, but whenever big lights are turned on at night, they don't show any reaction. They just go about their business. Same issue with the light coming from the computer monitor. I've resorted to putting cardboard all around my Ts' enclosures at night to make it more comfortable for them, but I don't know if it's that big a deal. I always get mad at people when they go in my room and turn the lights and especially if they leave them on after leaving. Sometimes my sister will even taunt me and flip the lights on and off and on and off, just to make me mad. It's not all the time. Usually my lights stay off, but I need to turn them on when I'm reading or doing homework or whatever. Because the Ts don't show any disturbance, does it mean that they don't care? What do you all think?
