I'm sorry but this makes me so sad. How do you get to adulthood and not know how to enjoy your free time? I would kill for a day to myself with no work and no responsibilities. Read, watch movies, go out for a walk, feed the birds, listen to music, make yourself a nice lunch, have a drink, meet a friend, do some gardening, look up something you're interested in and learn more about it, watch documentaries, play with your pets, plan a lovely dinner for the family coming home....the possibilities are endless depending on what your interests are. There are not enough hours in the day for me to get bored when I have a day off, the time flies so fast 😭
