I need reassurance, does your 2 year old feed off others energy

I notice My daughter feeds off of other people’s energy, whether it be adults or kids. She literally imitates everything she see and hears too. So I have decided to not let her watch certain Disney movies where the characters call each other names or act out. It’s made a difference. On another note, I take her to a school program where I attend with her for 2.5 hours 2-3x per week. There is another little girl that always shows up scowling and grumpy in the morning. My daughter will try to engage with her and offer her a toy but if the little girl is angry and my daughter is rejected, my daughter feeds off it and will then want to hit her and it becomes a rough morning!!! I think I just need reassurance that this is normal. I sometimes feel like a bad parent or wonder if I’ve done something wrong. What can I do in these situations. I can see the other mom thinks my daughter is the problem.
