They'll then go Jogging/Walking together. Step 2 - Click on the leading Sim, select the interaction you want to run (Jog or Walk) The request can be refused if the sim has one need in yellow or relationship is not high enough. If you select the wrong one, the other sim will not be put in the correct outfit and will not have the correct skill gain. Select the correct option for the interaction you want to run next (the mod includes a go for a walk interaction, but the Sim following system should work also on other mods doing the same).
This mod allows you to send two sims for a Jog or Walk together. Please follow the instructions, making this mod work was a pain in the arse.
