What’s this strap for on the manual transmission hump

You might be looking at this backwards. LOL Truthfully I'm with you I like having my Lady of 28 years with me when cruising. Once in a while she will still flip up the armrest and slide over. How many more years do I have until this stops? 51 minus 28 = 23 x (pi) minus menopause = Y ?
Menopause sucks they are a different person almost.
