When You Grow Up You'll Understand Shirt – Classic Guilt Trip Tee for Future Regret

The universal phrase that ends every argument and starts every lifelong therapy session. This shirt is a wearable eye roll for anyone who grew up being told they’d “get it someday.” Spoiler: We grew up. We still don’t get it.

Perfect for GenXers, exasperated parents, and anyone raising their own confused mini-me.

Why You’ll Love It:
• Nostalgic phrase served with generational trauma and a smirk
• Soft cotton that won’t scratch your unresolved issues
• Ideal for family dinners, PTA meetings, or silently judging your own kids
• Looks great under a cardigan of disappointment
