I have 4 sons...and no daughters!
I figure since I am missing out on not getting to dress up a girl in cute pink flowery stuff

, at least I'm benefitting by not having to pay for a wedding!
We do plan on hosting a rehersal dinner when our sons marry...but of course it won't be nearly the expense of a wedding.
For our wedding, my parents paid for most of it. Dh and I paid for our rings, honeymoon, limo, and everything about my attire except the dress/veil (so shoes, lingerie, hair and make up services, etc.). Dh's parents contributed $500 towards the rehersal dinner (covered about 1/3 of it). My parents paid for everything else, total of about $15,000. This was back in 1998
