Your words deeply moved me. They woke me up and showed me how often I've been thoughtless, just because I've been so caught up in work and life's demands. But at the same time, it's really stressful to always worry about every missed call, message, or email. What if I don't get another chance because I'm gone or they're gone? That's too much stress for anyone to bear.
Life is full of regrets, and maybe that's not entirely a bad thing. Nothing in life is perfect. I'm not saying we should be thoughtless and selfish, but living in fear of missing out on something like expressing love to someone or not responding to their call or message isn't pleasant either.
