One word ties a family together: love.
Now, sometimes, dislikes may pop their ugly heads in from time to time but love is the glue that keeps a family together. If I ever get upset with my other half, all I have to do is remember the moment he made me smile or laugh. This trip down memory lane could take a few hours (or days), depending on what ticked me off. However, I still love the big lug and having a toddler only further cements it.
Thus, at the end of the day, despite all the hardships you may have endured, just look forward to ending it with the most important part of your life – your family.
