Being helpful!

Today I bought my roommate a half gallon of milk to show my appreciation to him. He loves to drink milk and I noticed that he was getting low so I went to the grocery store and bought milk for him just to be nice. He was very grateful and pleased with my gift to him, and liked it a lot. It was honestly the least I could do, he has done a lot for me. I felt good after giving him the gift and would like to do good things for others more often.
