LW#1: Your gf has worn the same bra for two weeks? And you noticed? You are ahead of the game my friend, ahead of the game.
For your consideration: Are you sure it's the same bra and not the same, say, make and model? Because I and other women I know, especially if we have unusual sizes or certain fit requirements, tend to buy multiples of ones that fit. I'm just going to have a moment here to remember my old Warner tencel bras. I wore them all through college and after. God, we need more tencel bras. Perfect material for holding up the girls, really. The underwire never poked or did anything but lie flat against the ribcage. Oh, Warner, please, bring those bras back!!!
Anyway, they all were either light pink, light yellow or white and I had about 12 of them that I guarded jealously. And after a while I'm sure they all looked to be about the same color. But they were different ones.
The other possibility is that your gf knows that if she washes her bra, it might degrade the fabric ever so slightly. I myself am a more frequent washer, as I find it helps the fabric go from stretched to reset. That mean perkier silhouettes, which I am sure we all are all about.
Anyway, I'm here to say this behavior is normal. And congratulations for finally finding a woman who's willing to take her clothes off in front of you.
LW#2: Who cares? Why tell some ancient lady something that will upset her because the principle of the matter is that important? Look, she's at death's door, she doesn't call much, she doesn't need you trying to upset her on purpose.
Why even ask this? Are you mad at her for some reason? Work that out and forget about it. You keep making this out to be other people being greedy because of a will or whatever, well, what about you being provocative when it's not your place?
LW#3: Lots of sarcastic comments on her FB status updates.
Seriously, the thing is, you need to call her on her materialism while also making it clear you're not doing this out of jealousy, but out of your finding her behavior and attitudes repellent. Remark on what appears to be her complete lack of compassion for those doing without, and remember to add, "There but for the grace of God go I," because that is honestly the truest statement in the world. Anyone with any stability in this world — financial, emotional, health-wise — is a lucky lucky ducky, and with great luck and wealth comes great responsibility. I've volunteered in prisons, soup kitchens, mental institutions and women's shelters in my day and "those people?" they are all us.
Okay, off my soapbox now.
LW#4: They have forfeited. Pet care? Getting a weekend of kenneling is easy. Even scheduling a neighbor two months in advance to feed and walk dogs is easy. They sound pretty disorganized. Let them know that you couldn't wait and invited another couple. But nicely.
For the love of all things holy, don't let stringer-alongers ruin things for everyone. They deserve to learn from their mistakes. And they will deserve another invite to somewhere at some time.
But for now, doubleyoo tee eff evah.
