Yup that is very, very good tip to remember!! Learned that the hard way, when we used to live in an apartment and my hubby accidentally latched closed the glass sliding doors after his lunch as he went back to his work. The sliding doors were the only access point to our small garden patio and going back indoors...had left my cellphone inside, and temperature outside at the high 90's yuck! Stuck outside for over 30 minutes, debating, should I risk it and try going over the fence, but opposite the fence is a sloping ditch..will not work for me and it was going to be hotter too as the afternoon progresses.
Luckily my 3rd floor neighbor heard me shouting and was kind enough to contact my hubby. Looking back it was so funny..was also trying to see if there were some folks on the parking lot side of the opposite apartment complex going back to their cars after lunch. It was my shouting to one guy at the opposite complex that my 3rd floor neighbor heard heheh! She kept me company for awhile thru her balcony till my hubby returned home ...The 2nd floor apartment right above us was empty at that time too. Luckily too my hubby's office is just about 10 minutes away so he was able to return home quickly grinning with apology
