Some people are very particular about how they squeeze toothpaste out of the tube and can get really annoyed if someone borrows their tube and does it the wrong way.
Do you squeeze your toothpaste from the bottom or the middle of the tube? Or does it not matter to you?
I always squeeze my toothpaste up from the bottom and it used to really annoy me if my husband used my toothpaste and squeezed it in the middle.... I've settled his hash on that one by buying a toothpaste now that he hates the taste of, so he never borrows it now mwahahahaaaaaaaa
From the 'middle' until there's none there, then squeeze contents remainder to top, & start in middle again! I find this the easiest way, 'cos if you hold at bottom, the tube 'falls over', which REALLY gives me the s@&$-!
So 'centre of gravity', so to speak!
