My neighbor wants a key to our back gate as a shortcut to the bus stop. Am I being unfriendly by saying no?

Our back gate opens onto a narrow service lane that reaches the bus stop in about three minutes. Walking from the front of the houses takes closer to ten.

My next-door neighbor discovered the shortcut when we invited her through after a block party. Last week she asked whether she could have a spare gate key so she could use the route on work mornings.

She asked casually, as if borrowing access were the same as borrowing a ladder. I said I would talk to my spouse. Since then, I have thought of a growing list of reasons not to do it.

The gate leads through our fenced backyard. Anyone using it passes the kitchen windows, the patio and the door we sometimes leave open while carrying things outside. We also have a dog. The neighbor likes him, but she does not know when he is loose in the yard. A key could be copied or kept after one of us moves. Her schedule could change. A simple shortcut would become an open-ended access arrangement.

None of these concerns mean I distrust her. That is what makes the answer awkward. She is quiet, dependable and has watered our plants when we travel. If anyone were a safe person to help, it would probably be her.

My spouse is firmly against giving out a key. He says we can occasionally let her through when we are already outside, but permanent access to our yard is different. I agree. I also know the front route adds time to her early commute every day, while letting her through would cost us nothing on most mornings.

I considered offering a trial month with a rule that she texts before entering. That solves none of the basic issue: we would still need to check our phones and make sure the dog is inside. The shortcut would save her seven minutes by transferring a small daily responsibility to us.

The clean answer is probably, “Sorry, we are not comfortable giving out a gate key because of the dog and privacy, but if we are outside you are welcome to ask.” I worry the reasons invite negotiation. She might promise to text or say she will only use it when the yard is empty.

Would you give a brief no without details, explain the dog and privacy, or offer limited access at set times? Is there a way to decline a practical favor without implying that the person asking is untrustworthy?
