“A false friend and a shadow attend only while the sun shines”

Simplified Meaning:

Imagine you have a friend who only wants to hang out with you when you have something fun to do or when you are happy and doing well. But when you are feeling sad or going through a tough time, they disappear and are nowhere to be found. This saying compares that kind of friend to a shadow, which is only around when it's sunny. Just like a shadow vanishes when it's dark, a fake friend leaves when things get tough. For instance, think about a student in school who is very popular when their parents throw big birthday parties with lots of food, games, and goodie bags. They have many friends around them during these parties. However, if their family can't afford parties anymore or they have personal problems, some of these 'friends' might stop talking to them. This shows those 'friends' aren't true friends; they are like shadows, sticking around only when it's easy and fun. To avoid this kind of disappointment, you should appreciate and hold on to friends who stick by you in both good times and bad. Real friends are like siblings who support you no matter what. Surround yourself with people who genuinely care about you, rather than those who just want to benefit from you when it’s convenient for them.
