And why would you want to test your theory? It seems a little strange lovely Doggie - you sound fed up again so why make it worse?
Besides, if you want to measure how much people do not care about you, a day is hardly a fair yard stick. Circumstances could stop people calling you for a day that are not a true reflection on how they may think of you. You'd need to do a couple of weeks really - like any survey, a broader spectrum gives more truthful results.

If you're feeling lonely, get out there! Don't be afraid for YOU to phone your friends and see how they are. Friendships are always better when both make an effort - like your buddy who came over when she had the house redecorated. You, although worried beforehand, had invited her to stay with you and ended up having a good time. Worry less, live more.

Hugs.
