Night Walking. Is it abnormal and is it safe enough?

Hello guys, i am a sixteen year old boy who enjoys walking out at night(alone), and i live in suburban Colorado. I was wondering if it was weird for a person, in general to enjoy a night stroll? I love the chill from the fresh watered lawn, and the empty sidewalks where i can spend my time alone. I walk between 9-11 p.m. which is legally permitted in Colorado, and i usually go with my dog (small, and wimpy). Do you guys think this is a weird habit, and do you think i am safe enough? Thanks. Mom's been nagging, hope to see some good responses. Thanks.
