So: thmyl = the mile (or the mill) lbt = light (l i g h t → lbt? But 'g' 'h' missing, b instead of 'igh'? unlikely) Better guess: lbt = "about" (a b o u t) = bt, not lbt. No.
But "lbt" could be “light” if b = gh? Unlikely. But if phonetic: "lbt" = "el-bee-tee" = LB T — initials? thmyl lbt batl fyld dyzrt kwmbat
But maybe it’s “lbt” = “lubit” (love it?) — no. So: thmyl = the mile (or the mill)
So maybe original is thmyl = mobile? m o b i l e → mbyle? no. But if phonetic: "lbt" = "el-bee-tee" = LB T — initials
I think the most likely intended phrase is: — but “about” = "a b o u t" → "abt", not “lbt”. Unless 'l' is a mistake for 'a'? No.
But maybe original phrase is: — but "lbt" would be "long" (l o n g) → lng, not lbt.
