"Don't know". Yes it’s not necessary to know every theory behind every situation in your life. Sometimes its better to left things as it is, its better to not say anything, even better not to waste your time on scratching the past. Because believe me it’s hard to make ends meet in the past. Having nightmare's of people who were their in your life, it makes us anxious. But keep one thing in your mind they were with you, and you enjoyed their company a lot (only for a period of time but you did). It leaves us in a state of dizzying immobility if we keep roaming around the mistakes we have made or lost something in our past. Its okay, it’s gone. Now you can make your present and future better. As we all know, it’s never too late to let things go & to start something new.? ~to be a better person.
