I'm with you...it is weird...like I'm looking inside some else's undie drawer...not very comfortable. But, having said that...we do go to them and I do buy things. I like to think that the person would like for me to love their belonging.
My DH always likes to remind me to keep in mind what is really important...when you are gone..everything that seemed important to YOU is lined up and disposed of in a couple of days...so keep things in perspective. I think that is probably pretty good advice.
