Grandma's assvice

On my way home the other morning I was stopped by an older, grandma type, woman. Thinking she was going to ask me for directions or wish me a "happy morning", I stopped and smiled. She came within two feet of me and yelled "TAKE SHORTER STEPS AND DON'T CLENCH YOUR ARMS"

I was unable act or say anything in response. I kept thinking "Wha??? Did she just...she did just give me advice on how to walk"

Before I could think of something clever to say in response she was gone.
