anyone else look like their boyfriend 😂

my boyfriend runs a gym and teaches boxing/kickboxing/self-defense classes and because I take the first class I show up with him, take class, then do my homework while he instructs his other classes, and then I leave with him. well last night he was talking to this lady who was new to the gym and was telling her about how everyone in his family trained and fought at one point, his dad, mom, stepmom, his sisters, and I happened to approach them at the same time that he was telling her about his sisters fighting to grab my stuff and she goes "is this your sister?" and so he laughs and says "no this is my girlfriend," and the lady replies "oh… y'all look alike" and this other lady who has been coming for a while and knows that we're together says "I know, don't they look like they could be related" and I'm just like… please don't say that 😂 this isn't the first time we've been told we look alike either, and I hate it because you know… nobody wants to hear that their boyfriend looks like he could be their brother. He always laughs about it but I always instantly get in a bad mood when someone says that. We're definitely not related, he's puerto rican and I'm black/white so we aren't even the same ethnic background 😂 like we're almost the same complexion but he's a little darker, and we both have curly hair (not even the same color, his hair is black and mines is super light brown) we both have brown eyes (but that's common anyway 😂) and our noses are shaped similarly but I don't think we look like we could be related, those are the only similarities I see in our appearances. but who knows, maybe the reason we were attracted to each other in the first place because we saw ourselves in the other 😂 has anyone else gone through this ?
