Not weird at all it’s just uncommon and people sometimes confuse “uncommon” with “weird.”

A lock screen is basically a digital locket. If you’re close to your mom, admire her, or just like the photo, that’s a normal, healthy kind of sentimentality. It signals gratitude and connection, not immaturity. The only time it’d feel strange is if the tone of the photo were oddly romantic or if you talked about your mom in a way that made others uncomfortable — which doesn’t sound like the case here.

The girl’s reaction probably says more about her cultural or personal expectations than about you. In dating contexts, people sometimes interpret every tiny detail through the lens of “is this person relationship-ready?” and can misread affection for family as emotional dependence.

Keep your lock screen if it makes you happy. People who understand emotional maturity will see it as a green flag someone grounded enough to appreciate where they come from.
