very offended

I am a cna while in nursing school. I have worked all shifts, mainly dayshift at my ltc facility for quite some time. Since going back to school, I recently have been picking up 3 to 11s. During lunch one day one of my fellow aides informed me that the nurse the other night asked her if any of my work was getting done since I was being "too friendly" with another male aide (with whom I was working alongside helping transfer and change our residents). I take offense to this first of all because I was doing a double and already passed my linnen and fixed my beds and passed briefs hours before she even arrived. At 400 my charting and toileting was also done. I helped transport, pass trays, and feed. I even took a 5 minute lunch because lunches were running late, barely even stopping until I was 75 percent done with my assignment. I did all my work by myself only asking this aide for help to transfer. I showered a resident after he already put himself to bed because he was independent and only asked the male aide for help to shower a very difficult resident. My assignment was completed by 9 and I didnt take my 15 min break. I have worked with this nurse many times before and she likes to make snippy comments. However she is young and not one of the worst nurses ive worked with. Shes seen that I take my job very seriously and leave no stone unturned. I am offended that she thinks I am flirting with a man old enough to be my father. All she had to do was look and see that the residents were in fact in bed and changed at 10pm. In fact, the aide that usually has that assignment is quite lazy and wastes A LOT of time sitting in the nurses station every night. This nurse even knocked on the door before entering a residents room because "we probably wanted to be alone". I am beyond offended. This aide is a good friend and one of the only who is not fake and will help you. I go around helping everyone and occasionally ask this aide for help when I need it and this is how I am treated? Its not like I sat around with him all night and did nothing!
