Even though they're my friend, I sometimes feel dissatisfied😮💨

(Using a picture to make this less of a dark history) Complaining to someone feels like talking behind their back, but keeping it in makes me feel like I'm going to hurt myself. When a friend messes up, I choose to stay silent or give subtle hints because I'm afraid of ruining the relationship or seeming petty. Sometimes I can't help but wonder: is this carefulness because I care too much about this relationship, am I just being too concerned about appearances, or am I actually just too small-minded and nitpicking? Today, I happened to hear someone say that foodies can't be bad people because their minds are always on food. Unfortunately, I'm probably not a foodie. I read somewhere before that lions have a 'hidden little notebook' in their hearts. If you step on their dignity or cross their line, they silently deduct points. The day the score reaches zero is the day you part ways forever. It really is like that. But, coincidentally, both my friend and I are Leos. Relationship grades are so difficult. I still need to learn how to find the best way to cope and adjust between 'expressing my true feelings' and 'being considerate of the other person'.
