Here is a wise proverb concerning friendship that may seem strange at first glance. Having a friend is a wonderful thing - but there are friends who are what some call, "high-maintenance" people. They are the folks who start out as friends - but who soon so dominate your time that you start feeling like you want to avoid them. Yet the more you pull away - the more they seek to dominate your time. You wind up spending hours listening to them every day - and in the end - you wind up almost hating to see them - see their texts - or see their number come up when you look at your cell phone. This is what God is warning against in this proverb.
Friendship does demand some time spent together. This proverb is not encouraging us to be distant to everyone - and rarely spend time with each other. It is just using hyperbole to warn us against being the "over-needy" friend who seems to have to spend every waking moment with their best bud. The warning is to rarely let your foot be in your neighbor's house. The concept here is actually more that you rarely let your foot be there by your own choosing. What is advised is to be a good friend in life - but to be careful about how often you show up at their house. If you are invited, that is one thing, but when you are coming on your own constantly, it can begin to be a bother to them. Therefore, when it is your choice, be careful, be wise, and be somewhat infrequent. Don't be rude - just let your friend be the one who primarily initiates you coming to their home.
The word "weary" is telling us something important here. It lets us understand the hyperbole that is being employed in this proverb. We need to be careful to not "weary" someone else. The Hebrew word used here is "yisbaacha" and it means to be sated or full to the point of sickness. You know the feeling you get when you have eaten so much that you are about to throw up? That is what is being described here - in fact the same concept was used just a verse earlier to speak of eating too much honey. Now it is being used to describe a friend who spends too much time with you - and you are 'sated' with their presence to the point of being - honestly - sick of them. The warning here though is to us! Don't be that kind of friend. Be a friend naer enough to be a blessing - but yet still far away enough to NOT be an annoyance. It takes a wisdom to be able to discern which you are being.
