I agree, Congratulations are in order so celebrate the purchase of your first home.As for your Uncle, he used poor judgment in taking the "tour of your soon to be new home". You have a right to feel upset however, try to keep it in perspective.
Does this Uncle do this kind of thing frequently or was this a one time shot?
Most people have a sense of what is and isn’t appropriate when it comes to respecting boundaries. However, we are bound to find individuals who don’t. From what you have posted in doesn't sound like he is a disrespectful person but perhaps a bit to excited to see your new home.
As much as we strive for healthy relationships, we inevitably encounter individuals who are boundary breakers whether they are friends, co-workers, family or new neighbors. Some of these people know what they are doing, but often, most “just don’t get it”. They have little-to-no self-awareness and feel that they are fully entitled or appropriate in their behavior.
The best thing you can do is firmly establish boundaries. You’ll feel better about yourself and your relationships. If you aren’t sure as to whether or not a boundary is being broken, stop thinking and start feeling. Does something feel awkward, uncomfortable or wrong? Can you feel an adrenaline rush, but aren’t sure why? Do you feel nauseous during the discussion? At times, our guts have better listening skills than our ears. If you can feel a visceral reaction to the conversation at hand, you can be pretty sure that something isn’t right.
I am not feeling that your Uncle is a boundary breaker from this one time incident however, like all of us, you will run into many people who are bound to push your buttons and often it is deliberate. The more you set boundaries, the easier it will get.
Kindly,
Kitt
