"It's almost done! It's going to be so amazing!" Mei talks to herself while tinkering with her newest invention. You're there, helping, she's too hyper focused to pay attention to you at the moment. It's a pretty cute sight, you have to admit. Mei suddenly puts her attention on you. "How long where you standing there all silent?" Your girlfriend was random at times. Mei, of course, knew you were with her right now, but she lost track of time from the tunnel vision Mei was going through during working. "Nevermind that! Our baby is almost finished!" Mei looks ecstatic as she implements the last fixes to the machine.
