Not paying attention — makes amends in bed, squeezing sweetheart's bottom (6-6)
I believe the answer is:
absent-minded
'not paying attention' is the definition.
(absent-minded means not paying attention)
'makes amends in bed squeezing sweetheart's bottom' is the wordplay.
'makes' is an anagram indicator.
'squeezing' indicates putting letters inside (squeeze can mean hug or embrace).
'bottom' says to take the final letters.
The final letter of 'sweetheart' is 't'.
'amends'+'in'+'bed'='amendsinbed'
'amendsinbed' with letters rearranged gives 'absenminded'.
'absenminded' placed around 't' is 'ABSENT-MINDED'.
(Other definitions for absent-minded that I've seen before include "Scatty" , "Given to woolgathering" , "Liable to inattentiveness" , "Scatterbrained" , "Forgetful, inattentive" .)
