[header] How to plan an anti valentine's day party [title] Invite your single friends. [step] Who you invite is important. If you have friends who are in relationships, they're probably doing something romantic on valentine's day. <sep> (A) Call them up and ask them if they need help organizing their party! [substeps] To include your own friends, try inviting them to various valentine's events. For example, you can have a friend who recently went through a breakup come together for a valentine's day party. (B) Instead of inviting couple friends, invite your single friends who may feel lonely or left out on valentine's day. [substeps] However, you may have some couple friends who don't celebrate valentine's day or who are in long distance relationships. (C) If they're in a committed relationship, you should invite them. [substeps] Ask at the same time if they'd like to go out with their single friends or to plan an out of town party. (D) However, if you're split up or trying to just try some new activities, inviting them ahead of time will make them feel nice as well.
