Ignorant people

I rely don't like to rant about my problems but today I was walking with my boyfriend in the mall and some random lady came up to us in the mall and She said, "I've seen you guys walking around in the store holding hands, you trying to hold him, him picking you up. Super cute couple." the she asked our ages I'm 19 and he's 27. And then she just got this look like he was pervert or something. My boyfriend got the same feel about it as well. We've been together for 8 months. Do you guys see the problem of the age difference or do you think it's okay. Either way I'll still be with him because I love him no matter what
