And is this the right TL for the left panel? The situation is talking about how he became so reserved due to not wanting to "steal other peoples' time", so it feels strange to say that his carefulness was stealing peoples' time/lifespan. It seems like it would follow more to say "I was always careful around others, to avoid stealing their time (by limiting interaction with them)". Then that's contrasted with him talking afterwards about how he realizes that having meaningful relationships doesn't feel like he's wasting peoples' time, as part of his growth.
