How to friend someone on facebook without it showing up on my friend news feed?

This girl sent me a friend request. I am not her boy friend, but my mom will think she is my girlfriend. Is there any way to accept her request without anybody knowing?

you cant everything that you do on facebook gets posted to the
newsfeed automatically the only thing you can do is if you have someone
specific that you dont want to see your posts add them to the
restricted list and they wont see your posts you can find the restricted
list by going to settings then go to blocking should be under there
