"Hydro" refers to our electric bill
If my room-mate did not want to pay for his half of this months hydro bill and I used his credit card to pay for his portion, can he sue me? We got into a fight and he thinks I owe him money because he's taking back a gift he gave to me last year. This is what sparked his wanting me to pay the electric bill all myself. Many times in the past he has let me use his card to make payments for him because he is lazy. This time I did not have explicit consent but I used his credit card to pay for his portion of the hydro. His portion of the bill is 50% but I made the charge equal to 40% of the balance (I paid the rest). Now he is saying if I don't pay him back the $2800 he gave me last year, he's going to sue me for the $200 charged on his card by me.
