You really don't know a person. Even after all these years. My boyfriend and I have been going out for 9 years and 6 months. Blowing out our birthday candles together. He picked the candles. 

Me: "Chris, I wanted to blow out the green candle! Do you see color or just the candle?" 

Chris: "Just the candle."

A woman started to talk to me in the locker room after my workout. She is 340 lbs. overweight. Her goal is to loose weight for her knee surgery. She was fired from her job due to her weight and dealing with her her mom alzheimer's.

She smiled regardless - and said, "I'm going to the pool, it's the best after my workout. You should try it sometime." I declined because of going to work. 

However, I congratulated on her accomplishments asked for her name - Sherri. 

No matter how hard to workout, remember those who are also fighting their battles around you. Learn their names and say hi.
