A friend = oneself

Let me tell you a true story! I have a good buddy who recently made some money, but he seems to have discovered that his wife is cheating on him. He wants to convert all his money into coins so that when he divorces, he won’t give her a cent. Last night, we drank together, and he wanted me to recommend a coin. As the drinking progressed, I learned how he found out about his wife's infidelity, and I was really taken aback...
He doesn’t smoke himself, but he has a few-month-old son. When his son was crying during the breastfeeding period, he surprisingly smelled of smoke... I was also shocked and speechless at the time, trying to comfort him while recommending a coin I recently liked, which I also bought, namely $SOLV .
