Affection is the lightest, longest and irreplaceable, but sometimes it can be remedied if it is not put first. Always come back. Friendship is the strongest and deepest, it may fade, but it will not be forgotten. Sometimes it will worsen or even reverse, but it can basically be relied on. Love is the strongest and the easiest to change, and time will be diluted, but if true love does not disappear. The problem is that it can be replaced, and not everyone can always be trusted. In different situations, the importance of the three is different. Taking life as a whole, the order you can always have is the order of topics, and the most obvious order you feel is the opposite order. What I can't give up is family, what I can't forget is friendship, and what I will never forget is love.
