Do you tell your opponent's that they have a trigger?

I have a group of friends where I'm quite a bit better then them since I've played longer and played competitively. They got into it some of them because others were getting and some because of UB sets they liked. No shade, just context. Since cards nowadays are more complicated and synergistic, it ends up with them missing triggers. Sometimes a few, sometimes a lot. My latest game all of them were constantly missing triggers on their turns. From forgetting to switch the monarch to drawing for monarch to creature ETBs to end step effects to upkeep effects to lifelink to +1/+1 counters. It felt like I was a nagging mother telling them that they were missing stuff. At some point I just, stopped. The game was flowing smoother but man were they just falling behind because of the missed triggers. Should I feel bad that I'm not reminding them? It was clear they were getting a little annoyed but it's their deck! It's not my obligation to remind to remember all of their cards in play.
