We meet a lot of people in our lifetime and we cross paths with a lot too so, we just need to make it a part of us to try as much as possible to learn from anyone that we will cross paths with because nothing lasts forever.
No need to sit back all jn the name of being moody because we lost someone especially if it is due to the decision of the person. We just have to move on while maintaining positivity.
