I dunno if I have shared this, but your Aardvark suffers from Short Attention-Span Relationship Disorder. This is NOT equivalent to Roving-Eye Disorder.
If someone is in my immediate orbit, all is well. Regular communication, jollity, a Good Time Is Had By All. If I move away, or, perish forbid, someone else moves away, they are dead to me, practically speaking. I am not describing a jerky "How DARE they leave me?" passive-aggressive response to abandonment, no, but rather a "you are not there to push my 'attend to me' button" response. When someone dies, then they are gone. Period. I do not mourn much, or well. It took over 48 years for me to actually mourn my Momma's demise.
I do in fact view this as pathological, and I have suspicions as to its genesis, but there it is. It bugs me, but I do not wish to feign what I do not feel; neither do I want to ignore them wot I wish to keep in touch wiv.
Please be patient with me. I'm trying.
