There is so much offense in this world! Seems like people are always looking for it, and they absolutely can find it! Take the gift (because that's what it is), and just be grateful! If there is a hidden message, it has probably already been brought up in many other ways. Don't go looking for one! There is also the possibility that you have mentioned in the past, whether you remember it or not, that you would like to either lose weight, get in shape, feel better, etc., etc. Most likely, it was just something nice he thought you might like to have. It could have been a blender, or a string of pearls. The fact is, it's a gift. Be gracious, and use it if you want. The great thing about a gym membership is the final fact that it will help you get and remain healthy! No down side to that!
