Hey there, gentlemen, don't forget that one week from today is Valentine's Day. Consider the ease with which you get allocations from the household budget for your racing addiction, and then make absolutely positively sure that you get flowers, candy, a fancy negligee, or whatever else it is that you know your better half would appreciate getting from you. Whether she'll say "You know I need to lose weight -- why'd you buy me candy?" or not, she'll be tickled that you thought about her instead of that new cam that you've been talking about over supper for weeks on end. Get a mushy card, too, and maybe put in a gift card from a store where you know she'd shop for stuff for herself.
If you really need a new vacuum cleaner so she can pick up the oil dry that you track into the house -- get it and give it to her a couple of days BEFORE next Wednesday. I got a new vacuum last weekend -- plenty of time in advance of Valentine's Day.
If she lets you go racing -- make sure you let her know you appreciate her.
