It's difficult to judge someone else's happiness based solely on wins or losses. However, you highlight a fascinating truth:  gambling victories can trigger a rollercoaster of emotions, including envy. It's natural to feel a pang of jealousy when a friend hits a jackpot while you walk away empty-handed.  Imagine two athletes – one wins the gold medal, the other finishes just off the podium.  The silver medalist might feel a flicker of envy, but it doesn't diminish the gold medalist's achievement.

The problem arises when envy translates into reckless behavior.  Following your friend's "footsteps" by exceeding your gambling budget to chase a similar win is a dangerous path.  It's like a gambler throwing good money after bad, fueled by envy rather than sound strategy. However, there's another side to the coin.  Celebrating your friend's windfall, especially if it translates into treats or shared experiences, demonstrates genuine happiness for their success.  Imagine a group of friends celebrating a teammate's victory – individual joy intertwined with collective pride.
