out of the blue

so lastnight im in my bed in that good deep sleep and my phone starts going off...i check the number but i dont recognize it so i dont answer and go back to sleep but to my surprise about 10 mins later it rings again i dont answer it then my room phone rings and itz a voice i havent heard since september....a guy i used to talk to but we stopped talkin cuz he put me on "punishment" so i was mos def surprised to hear his voice and he starts talkin to me and askin me how im doing and im like what made u call me and he says ive been thinkin about u a lot lately and im like yeah right......so we had about a 15 minute conversation and he wants to know when im coming home and what my schedule is.....(we go to the same church) it was just crazy but ima mos def keep him at a good distance i dont know his motive!
