My best friend's son does MA-fighting, in which he is very good. To be honest I could care less about the whole fighting world especially for a 6 year old, just as she is not really into the whole academic world. It is hard for me be happy for her when her son wins a fight just as she is not excited when my DD accomplishes something academically. Needless to say we usually limit academic and fighting talk to the bare minimum.
It could be that your friend is just not as impressed with academic accomplishments as you are, or maybe your comments are making her feel like you are raising your child's accomplishments above hers.
In any case, I wouldn't consider it a big deal if a friend does not feel the same awe as you do about your kids. There are many things, besides the children's accomplishments in which to talk about.
