Unless your wedding consists of you and your spouse to-be going to Las Vegas or something of that nature to elope, you'll almost certainly have to put some thought into who to invite and who not to invite. For a small wedding, just immediate family will have to suffice, and most people will generally respect that scenario. For an even larger wedding though, there may be people you'd rather not attend. This typically includes co-workers, distant family members who hold grudges you haven't talked to in a long time, or friends of the family that aren't close to you but attend all family functions for some reason, you know the types.

For people that are only dating someone that needs to go to the wedding, you don't necessarily need to invite them. But be careful how you approach that with the person, and seating arrangement can help prevent conflicts from those type cases.

Be prepared with answers if someone bumps into you that expects to be at the wedding that you wish would just go away. Polite responses such as the wedding being too small to invite everyone, or the heat (or cold) would bother them, location, or better yet tell them your parents were responsible for wedding invitations (tell them that only if they don't know your parents), etc.,.
