number neigjbor

so i texted my number neighbor and i’m 15 and he’s 21 so i lied and said i’m 17 but i didn’t think it was a big deal but he’s rlly chill and like it was just a casual lil text but he’s just some kid in my area that’s rlly cool and my mom thinks i should tell him i lied about my age but like we aren’t gonna text again so like i feel like there’s no need. Plus it would be v awkward lol but my moms scaring the shit out of me about how i could get him in trouble if he did something but he didn’t so like can’t i just leave it be?
