End of Expectations... !!!!!!!

It was  just Yesterday, I was with my Friend Akansha near Vastrapur and we were talking about our life, our office, our happiness,pain everything, then I said yaar today I don't want to eat dinner. then see said no. you have to eat something ok. and tell me where you want to go for dinner. I said no .. then she said tell me yaar. I told ok lets go Jussi de Parathe.  She told ok done. And when we were going for restaurant I saw a old man, who selling incense sticks to the people who are sitting in the area of restaurant. then we order Paneer burji and 2 Parartha. Really that time I was not that much hungry yet I spend that much money in Jussi. then Akku told one more paratha ok.... I said no but she ordered for us. after having dinner the bill is Rs 250. and she told yaar now I have Rs50, I said don't worry I have. then we paid and leaved the restaurant. we just cross the restaurant area and that old man came near me and said please buy my incense sticks. and that time I and akku both are think that he was asking for money. but then I saw him and said akku , hey akku he is not asking for money , he is just telling me to buy his incense sticks. then she said ok and we back to that old man and asked for incense sticks. he said Rs20. I said ok give it to me and I buy it and akku paid to that old man. He said to me that I was not asking for money, I told you to buy my incense sticks only. that time I feel really bad and realised that that person not able to stand properly and he is just struggling for his food and managing to himself to stand properly. I saw him that his legs are shivering but still he was stand and watching his ends of expectation for money because except me no one buy this incense sticks. then we leave and reached our home. and I talked with my Mom and dad then friend, and just trying to sleep and suddenly in my mind a picture came that was that old man, and I just thinking, why this happen to him, where are his children's. don't they have any idea about that how their parents surviving. And the condition of that old man is not good, that I know and I regrate that why don't I asked him to food or his home so that next time I will help him with anything. Because when I spend Rs250 for dinner is don't means and actually we had not need to spend that much money for dinner. but we did.. and about that old man, he is just struggling for his dinner. O God please help him. I cried that I always telling to God. please give me this , give me that but what he asked to God????????
I don't know how can I help him but i want to help him, now when ever if i meet him again I will asked him for his home and take responsibility for his food... I wish that he will meet me again..
