If you start collecting your tears in a jar then one day you'll be able to tie someone who's made you cry to a chair and pour the jar of tears down his or her throat so that he or she can literally choke on your tears. Make sure when you pour the jar of tears down the person's throat that you pour it really fast to ensure that they'll choke. If they manage to just swallow your tears, that's a sign of strength or resolve or something, and all this collecting your tears in a jar stuff will have been for no other reason than to make the person who made you cry feel good about him or herself. Though, the "swallow my tears" thing is usually about swallowing your own tears. Swallowing someone else's tears just means you managed not to choke when someone poured a jar of tears down your throat.
This making someone choke on your tears thing is worrisome. Just start collecting your tears in a jar (do it by crying over an open jar!) then when the time comes maybe we'll just have you throw it in someone's face or pour it down the waistband of their sweatpants or something.
Happy Start Collecting Your Teardrops In A Jar Day!
