My Feeling Are Not Vaild

I took me and my family out and paid for some items. I didn’t think nothing of it and I was just think out loud about the price. Now, I paid for it they got it and I got shamed for saying anything about it. I felt attacked cause I wasn’t talking to anyone. Just to my self at least that’s what I thought, I didn’t direct it to no one, am I wrong?? Anyways… long story short I was told to keep what I think and my feelings to myself and don’t say anything and now I don’t know what to do with that. Was I wrong??? Any advice???
