One, but only if it’s her own lightbulb. Otherwise, I’m not the homeowner or the electrician, so it isn’t my call. However, I am familiar with the process, and would be happy to talk you through.
First, do we know that the light bulb must be changed right now? Are there more urgent matters at hand, like fire or glass on the floor? Is everyone safe? Do we have time to talk this through? OK, good.
The benefit of changing the light bulb would of course be having more light in the room. Is that your preference? Great.
The risk of changing the light bulb would be falling off of a ladder, but that’s relatively low in this case because the lamp is on the table and the likelihood of your needing a step ladder is minimal.
Of course, it’s another option to use a camping lantern, or light a candle or use a string of twinkling Christmas lights as long as that’s appropriate and safe for the space it’s in. What ideas might you have about that?
Or, you could choose to do nothing right now. It’s still daylight out, and the lamp is decorative, and perhaps you aren’t planning to keep it. I remember you’ve said that Aunt Mildred meant well when she gave it to you, but it really isn’t your style. It’s entirely up to you.
If you are worried even a little, call your contractor or an electrician. They may assure you that this isn’t an emergency, or they might want to talk with you in person to let you know of ways that they can help you make a plan for this. They might recommend installing overhead canister lighting fixtures, but I’m really not the person to ask about that.
What matters most is that you are making the decision in this that is right for you. I want you to be content with your lighting choices. Let me know how I might be of support.
There’s no pressure to make a rushed decision, take some time, mull that over, talk to your partner, and let me know what you think. And if you change your mind about it later? That’s ok too. It’s your lightbulb. You can do that.
