So, it was a computer joke about RAM not the best joke ever but at least it made sense... after explanation. Harold was really into his work, making sentient life was a very ambitious project. Thisa nodded, "Sounds like complicated work, there's a lot to sentience that we don't even understand in humans yet, I imagine its even more difficult to attempt creating it. What I'm doing is also related to robotics, you saw my notebook. What I'm doing tying create one that looks human, sure its easy enough to get the shape but there's so much more involved then just a human like skeleton. For one synthetic materials we have now are just... too prefect if that makes anyway sense, look at your skin now notice all the flaws on it, its just not smooth and uniform. Another part of it is tying to get the bot moving like a human, you've seen that we been able to build anthropic machines that walk on two legs, problem there is they walk too proper. If you ever watch someone walk or run there are irregularities, may not be noticeable but small things that don't make us perfect. Might be kinda odd really, trying to build an imperfect robot, but if we want a human like one they need to be flawed just like us." 

Thisa was really into the conversation now, its never too often she could find someone willing to sit down and listen to her ideas about her work. She took a breath and was about to jump into the next part of her speech when she noticed the time on her watch. She was going to be late if she didn't get moving right then, where did the time go?

"Oh- uh, sorry I just noticed how much time's passed, think I need to get moving or else I'll end up being late today. I'll catch up with you later Harold." She shouted down to Timothy, "And you as well, uh... oh right Timothy." With that Thisa started her way to next class, after giving a smile and a wave.
