"baby don't hurt me, don't hurt me, no more. Woah-owo-woah-owo-woah!"
But to be serious...I'd say love is sacrifice.I find that the days I love my wife most are the days that I inconvenience myself to make her happy. Knowing that your mild inconvenience brings SO MUCH joy to someone else is true love.
I'm a bit of a "man's man." I like sports and wouldn't be caught dead wearing metro-garb, but for an anniversary present for my wife, I signed us up for dance lessons and have been taking them with her...it makes her so happy it's worth the "lameness" of it...
I also am currently working at a job I HATE just so my wife can continue to go to school and work in a career she will love.
Love is sacrifice - big or small
