Infamous civil engineering juggernaut Jeremy Ghent sent this one to me o’er the Intarweb.

Variables:
A = Roommate 1
B = Roommate 2
C = Neighborly Fellow
D = Sugar
E = Bread
F = Milk
G = Cinnamon
H = Messy Sugary-Cinnamony Outline

‘A’ enters residence of ‘C’. ‘A’ complains that ‘B’ is eating his food. ‘A’ is certain because he keeps cleaning up ‘H’. And ‘B’ has never purchased ‘D’, ‘E’, or ‘G’. ‘A’ proceeds to complain that his ‘F’ is nearly empty and ‘A’ has not had any all week -> ‘B’ must be consuming ‘A’s ‘D’,'E’,'F’,and ‘G’ and leaving ‘H’ for ‘A’ to clean up. ‘A’ leaves residence of ‘C’ and proceeds to residence of ‘A’ + ‘B’. 147 sec later ‘B’ enters residence of ‘C’. ‘B’ states “Man ‘A’ is pissed off and I didn’t even do anything.” ‘C’ inquires as to the circumstances. ‘B’ states “‘A’ just walked in saw me and went to his room and slammed the door. ‘C’ asks what ‘B’ was doing at the time ‘A’ entered. ‘B’ responds ” Nothing I was just standing there eating cinnamon toast and drinking a glass of milk.” ‘C’ just shrugs shoulders and contains violent laughter.

Please solve for ‘B’ (Hint: ‘B’ likes to call dogs cats, is known to play drums, is generally noisy, has recently taken a liking to artificial water foul and apparently has the occasional hankering for Sugary-Cinnamony Goodness)
