Do you think one of the ladies was being rude about my size?

So I’m a tall girl….well young woman at 5’11”3/4. NO I AM NOT 6ft TALL! I am approximately 257lbs (not telling you my real weight).
Anyways when we were doing something called CPI training, when we were discussing how to handle students when they get aggressive of violence, one of the ladies said, “Well since you work with the littles and you’re so tall, it’s going to be very difficult for you to sit on those small chairs and it can easy break when you sit on it and holding on to the child when he/she gets aggressive. You should request bigger chair for you.” I did agree with her but it did hurt my feelings a bit. Another girl said, “Yeah she has a point. Someone your size can easily hurt someone smaller and you can easily break the tiny chairs. Plus you’re very tall. For the teacher Mrs. (Let’s call her N) is a little lady so it will be different since she’s petite and little. No offense.”
That really hurt my feelings. But I didn’t show it. Mrs. N (who I met and is very kind) is a little lady at about I am guessing 4’9”. The other assistant is about 5’6”.
