I hate when she's right

My sister was yelling ate a few nights ago because I wasn't wearing my chest strap all the time.

I told her constant wearing would weaken my trunk muscles, but she was having none of that.

It won't weaken your trunk muscles, she said. Email your physical therapist, she added. I'll bet you $10 she agrees with me.

I remember my PT telling me not to wear the harness I originally had on the chair for the trunk muscle reason, so I suggested we raise the bet. I then went to email my PT.

My PT's response: Don't worry that wearing the strap will make you weaker. It's better than reading your face, dummy. (The dummy was in my  head.)

Now I owe my sister $10.
