4. Go for a walk with your dog
Perhaps, you’ve already heard of people who celebrate Valentine’s Day with their beloved pet. Why not? I don’t consider those people crazy because pets are wonderful companions and sometimes it’s better to spend time with them than with people who don’t love you or don’t care about you. If you have a dog, why not hang out with him/her? Your dog doesn’t care what day it is and he truly loves you. If you don’t have a dog, but you have a cat, you can also go for a walk with your cat and spend a great evening with him/her.
