the principals of what you are saying is actually true, all objects have an attraction(similar to magnetism) to each other, it's how gravity works, (though obviously the attractions between the sun and the earth are on a much larger scale)
And it's only on these scales that you are likely to notice anything.
I think it could well have been the top-heaviness of the galsses that gave the effect you are describing, get two, and hold them by the very top, and i'm sure that you will feel no attraction.
