Most of the talk people do is in an unconscious state. They rarely think over things and talk to you. Keeping this in mind saves you a lot of energy. If you ask questions about what they talked and said in the past hour then most people fail to accurately recall and respond. Hence feeling happy or sad about the stuff they uttered is pointless. Don’t take it personally and ramp up emotions.
Talking
Everybody is shy to start a conversation but everyone wants to talk. People find it awkward, embarrassing, and weird to initiate a chat. Hence they won’t make the first move and simply wait and expect that the other guy understands this. But the others too think alike and in the end, only silence is shared. Avoid this and by all means, you take the so-called initiative, the train/flight/bus journey for the rest of the time will be at least exciting and entertaining, if not enriching. And you might learn something about something. You never know where the wisdom that you need at that point in your life comes from.
