i went school shopping with my mum and i saw a homeless man outside

i went school shopping with my mum and i saw a homeless man outside the shopping center, so i went up to him and he looked sad and cold. his  finger nails were really long and had dirt under them, had a few missing teeth, long gray hair.he was huddled up in a corner with a hat filled with 2p coins(english money)
his clothes were a good few sizes bigger and he was skin and bone. i gave him a packet of crisps and he thanked me, in a weak voice, and his blue eyes were filled with pain.
i felt like i completed a challange, i felt amazing when i knew i had given the homeless man- who hadnt eaten in days -something to eat even if it was small.
it made me realize that my life could be worst, i get food daily, i have a home, i have clothes- sure what i have isnt perfect and i dont like it, but i still have it. 
it made me feel like i had actually helped someone, that i was needed, that i made someones day better.
