curious🤔

i’ve found my next door neighbour cute and stuff since i was young and now i’m 16 and he’s 19 and i think he’s so amazing and so i found the courage to add him on snapchat but i don’t know what to message him like i cant just message him hey or streaks or whatever because i’ve known him for so long and that would be awkward and we don’t really talk that much so how do i start a conversation without being to cringey, childish or forward? xx
