There are lots of vacant lots. Ask the person you hate most to go with you to the vacant lot your friends have chosen for this coming Saturday. Tell this person you'd like to pick him/her up. Tell him/her you'd like to introduce him/her to your friends. There are many vacant lots, so you don't need a temple or a mosque or a synagogue or a church or a cathedral or the Vatican. Then all of you will stand in silence for a time. Tell your new friend thanks for coming, that his/her coming has blessed your day.
