Freshman year of college my son called panicked and said "Mom, you need to do me a big favor...my cup broke and you need to go to Decathalon and send me a new one"...gives me the style and size...off I go thinking "why me...should be the Father"...but being the Mom I do as asked....so I find the cups and locate the style and the size...and in my mind I am saying...No!!!...No!!! this is way, way too big...so I find a sales lady and explain my dilemma...she informs me that I am in the correct area.. so I tell her the cup seems way too big for my son...she tells me just for a hoot mail him the size small and tell him that I thought he was exaggerating and the small was more his size...we had a great time discussing sizes, delusions etc...in the end I bought the size sonny asked for as I did not think he would find it funny...and when I told him the story I was right...he did NOT think it was funny at all...
