Are you sure you understood her correctly? I'm just wondering because maybe she meant she'd be happy to share her faith and beliefs, but she just didn't want to advertize her faith like it's the newest fad or something. I don't know.
If she really meant she just didn't want to share her beliefs and faith, then no. It's not the typical Catholic view. I love talking to people about my faith and I pray with and for people all the time. My friends know they have only to ask, and I'll add their intentions to my prayer list.
In Christ,
