When I spend my Sunday afternoon with family I feel best about myself. Work in the yard together or take the dogs to the park for a long walk and a picnic is the best. Sunday evening with a good book is the perfect end to the weekend.
Try picking up a new hobby. Learn to do something that you have always wanted to try. Spend some time out doors. Do work around your house or go on a hiking trip.
Well I might be even more boring. I spend my time reading, crocheting, or on the internet. Every now and then we will go to a park-like place and walk.
