Silver would be the type of person to place a kiss against items that his S/O left kiss marks on. Lipstick marks on a letter? Or on a piece of fabric? He'll kiss it back and get butterflies in his stomach over the indirect kiss.
And his (nearly) inhuman ability to spot kiss marks even without lipstick. "This letter has a pattern of recently dried moisture in the shape of a lip..." type of deduction, and he has never been wrong about it.
