A day

Iam a 20 year old man , didn't explore much but most of the time I've been inside my house in my past Iam doing my college right now and..I don't want to yap about me much , so I was having a bad day , a Very bad one, and I was travelling to my home town from my college , as I was walking towards the railway station an old lady and her daughter in law asked me for help to carry their luggage and I accepted their request , as I was walking with them they thanked me so many times with a humble smile and suddenly, I felt better from the bad day I was suffering from , so what Iam saying is it's always better to put a smile on someone even though they are strangers, it also puts a smile on you.sorry for bad english
