Dear Heloise: Recently, I watched a flight attendant open up cans using a credit card under the tab. After I returned home, I had a black bean can to open and tried using the credit card to pull the tab up. No broken fingernail or sore fingers! I would guess that people who have arthritis would find this to be an easy way to open cans. — D.B., via email

MISSING KEY FOB

Dear Heloise: I was having trouble remembering to take my key fob when I left home until my husband put a safety pin on my fob. I just pin the fob to my blouse or other garment (or inside a pocket). I never forget my key fob now. I hope this will help some other forgetful person. — Shirlene B., in Arkansas

A HAIRDRESSER’S PLEA

Dear Heloise: I’ve been a hairdresser for over 18 years, and there are a few things that I’d like to remind women of when they make an appointment at a beauty salon. First, this is not a hobby; it’s a job. It’s how I pay my bills and feed my kids. I work hard and stand on my feet all day. So, please remember:

— To show up on time. Most hairdressers will make you reschedule if you are 15 minutes late.

— Do not cancel at the last minute, and no, I will not call a client and ask them to reschedule because you want their time slot.

— Don’t ask for a discount/samples or any of my equipment, especially my scissors.

— If your friends also come to me, please don’t ask me questions about their personal lives. Even if I know the latest gossip, I won’t share it.

— Referrals are welcome and appreciated, but I won’t pay clients to refer people. However, I will do a great job on their hair!

— Next (and this is awkward), bathe or shower before you come.

— Lastly, if you came in for a haircut, highlights, or any other service, I allow a certain amount of time for your appointment. If you need or want additional services, you’ll have to make a separate appointment. My next client is sitting in the waiting area, and it’s not fair to keep them waiting. Thank you. — Diana T., in Arizona

WEIGHT LOSS WOES

Dear Heloise: Since I am on a low-carb, low-sugar diet, jellies and jams are off-limits to me. But once in a while, a guy has to have a peanut butter and jelly (or jam) sandwich. Peanut butter on a no-net-carb tortilla is OK. For my fruit spread, I take several frozen blackberries and thaw them out in the microwave. If they aren’t sweet enough, I add a teaspoon of monk fruit and artificial sweetener. It is very satisfying and has few carbs. — Uncle Johnny, via email

DEHUMIDIFYING

Dear Heloise: If you live in a humid climate and are building or remodeling a house that has pocket doors, you may want to make sure that the pocket is sealed against outside air. I live in a house without such sealing, and moist air blows past the pocket door and raises the humidity in a 300-square-foot room to 75%.

A dehumidifier, which lowers the humidity to 40%, removes 2 gallons of water a day from the air and has been doing so daily for over a week. — Ron S., in Charlottesville, Virginia
