What to say?

so today was the last day of scool!! yay! lol and i walk home and sometimes theres this group of people i walk with and i only really talk to one cause thats the only one i know. but today there was this other guy walkin home so i decided to say sup and we talked small talk a bit. he was in one of my cles this semester and he didnt talk at all and stuff. anywho i come home and theres a friend request from him so i accept. and then he sent me a message asking if i want to do sumthing this weekend. i cant decide if i want to or not. i mean i dotn know him very well but theres a first time for everything right. idk what would u do or what do u think i should message back??
