Pet Peeve? When people ask for help training but....

So I help my coworker join my gym, I trained her for a day took her food shopping & explained to her how to food prep. She came back once by herself to the gym & hasn’t been back since which was weeks ago. I asked her yesterday if I would see her at the gym in the morning not in a pushy or condescending way. Just in what I thought was an encouraging “let’s do this” type of way. But she had the nerve to like get mad and act as if I was bothering her. She got like super flustered and was like “Not now DJ”! Keep in mind I haven’t bothered her or bugged her about going to the gym because I’m just not like that. I honestly prefer to work out alone because I look at the gym as my “me time” but if someone asks me for my help I will never say no. This girl asked me for help and she wanted to get a “summer body” and blah blah blah. But it just really makes me think twice about helping people When they asked me for a workout and diet advice. It just felt like a slap in the face.
