How do adults even have friends??

My life is so full of everyday grind- work, shopping, cooking, cleaning, preparing for the following workday, etc. I have no time to actually just drop everything and go hang out somewhere with a friend. 😔

Recently a girl gave me her number so we could maybe hang out sometime because we have both only been in Phoenix for a year and we have no friends here. But after a brief text conversation yesterday, we haven't reached out to one another since, and we probably won't. 😕
